  changes its Size. copies the contents Of the old block into the
  New one. CurSize And NewSize specify the Current And the New Size
  Of the block. If the New Size Is larger than the Current Size, the
  additional Bytes are zeroed. the old Memory block Is automatically
  disposed. note that the resulting Pointer will always be different
  from the old Pointer, even If the Size isn't changed. the Function
  can Handle Nil pointers And Zero blocks. }

  the given String, returns A PString To the Memory block. the Memory
  block's Size will be exactly one Byte more than the string's Real
  Length. Empty Strings don't Use any heap space, the Function returns
  NullStr In This Case. since NullStr Points To EmptyStr, the Function
  never returns Nil, So you can always de-Reference the resulting
  Pointer. Use DisposeStr To Free the Memory block. }

Function NewStr(Const S: String): PString;

{ DisposeStr - Disposes A block Of Memory ON the heap that Contains
  A String. the block MUST have been allocated by A call To NewStr.

  String) Or Nil, the Function does absolutely Nothing. }

Procedure DisposeStr(P: PString);

{ AssignStr - Assigns A New Value To A String Pointer that has been
  previously allocated by A call To NewStr, Or Is Nil. the old String
  Is disposed by DisposeStr, And the New one Is allocated by NewStr. }

{ --- String formatting --- }

{ format - formats A String And replaces placeholders by arguments.

  the format String can contain arbitrary Text. This Text Is simply
  copied into the Result. everything that Starts With A '%' Is
  considered A placeholder. placeholders are replaced by the
  Parameters given In the variant-Type Open-Array Args. the First
  placeholder Is replaced by the First argument, the Second one
  by the Second argument, And So ON. you MUST specify At least As many
  Parameters As there are placeholders, Otherwise an Exception
  EConvertError will be raised.

  the way A placeholder / argument pair will be Handled Is controlled
  by Some optional specifiers. the Line below shows the possibilities.

  Text In " " MUST appear literally, 'index', 'width' And 'precision'
  MUST be replaced by Integer numbers, And 'type' MUST be replaced by
  A character that specifies the argument Type.

  parts enclosed In angular brackets are optional, the angular
  brackets MUST Not appear In the format specifier, they are only used
  To Show the syntax.

    "%" [Index ":"] ["-"] [Width] ["." Precision] Type

  the different parts Of the format specifier MUST appear In the
  given order, And they have the following meaning:

    "%"                Begins the format specifier

    Index ":"          takes the Next argument from the Array entry
                       given by Integer Value Index. Normally the
                       arguments are used one after the other. This
                       part Of the format specifier allows To Change
                       This behaviour.

    "-"                Left-Justifies the Text inserted For the format
                       specifier. Normally the Text Is justified To
                       the Right. only applies If the String Is Left-
                       padded With spaces by the Width-specifier.

    Width              Integer Value that specifies the Width being
                       reserved For the argument. If the String
                       resulting from the conversion Of the argument
                       Contains less than Width characters, it Is
                       Left padded With spaces To achieve This minimum
                       Length. If "-" Is used To Activate Left-
                       justification, the String Is padded To the
                       Right rather than To the Left. If the String
                       already has A Length equal To Or greater than
                       Width, no padding Is Needed.

    "." Precision      Integer Value that specifies the Precision
                       used when converting the argument. the actual
                       consequences Of Precision depend ON the
                       argument Type. See descriptions below For
                       Details.

  the Index, Width, And Precision specifiers can also contain an
  asterisk ('*'). In This Case, the Real Value Is taken from the
  Next argument Array entry, which has To be an Integer Value, Or
  EConvertError will be raised.

  following are the characters allowed To specify the argument Type.
  note that 'decimal point' And 'thousand separator' mean that the
  characters contained In the global variables DecimalSeparator And
  ThousandSeparator will be inserted.

    D                  DECIMAL format. the corresponding argument MUST
                       be an Integer Value, Otherwise EConvertError Is
                       raised. the argument Is converted To A DECIMAL
                       String. If A Precision Is specified, the String
                       Is guaranteed To have At least A Number Of
                       Digits equal To Precision. If the String Is
                       shorter, it Is padded With zeroes.

    E                  Scientific (exponential) format. the
                       corresponding argument MUST be A floating Point
                       Value, Otherwise EConvertError Is raised. the
                       argument Is converted To A DECIMAL String using
                       Scientific notation. the String Starts With a
                       minus sign, If the argument Is Negative. one
                       digit always precedes the DECIMAL Point. the
                       Number Of Digits following the DECIMAL Point Is
                       controlled by the optional Precision specifier.
                       the total Number Of Digits Is always equal To
                       Precision. If Precision Is Not specified, a
                       Default Of 15 Is assumed, resulting In 1 digit
                       before And 14 after the DECIMAL Point.
                       following Is the exponential 'E' With A plus Or
                       A minus sign And up To 3 Digits indicating the
                       Exponent.

    F                  FIXED Point format. the corresponding argument
                       MUST be A floating Point Value, Otherwise
                       EConvertError Is raised. the argument Is
                       converted To A String using FIXED notation. it
                       Starts With A minus sign, If the argument Is
                       Negative. All Digits Of the argument's Integer
                       part appear In the Result. following Is a
                       DECIMAL separator And A Number Of Digits equal
                       To Precision. If no Precision Is specified, a
                       Default Of 2 DECIMAL places Is assumed.

    G                  General Number format. the argument MUST be a
                       floating Point Value, Otherwise EConvertError
                       Is raised. the argument Is converted To a
                       String using either FIXED Or Scientific format,
                       depending ON which results In A shorter String.
                       the optional Precision specifier Controls the
                       Number Of significant Digits (used For
                       rounding) With A Default Of 15. the Result will
                       contain neither unnecessary zeroes nor an
                       unnecessary DECIMAL Point. If the argument
                       Value Is greater than Or equal To 0.00001, And
                       If the Number Of Digits To the Left Of the
                       DECIMAL Point Is less than Or equal To the
                       Precision, FIXED format Is used. Otherwise the
                       Result Uses Scientific format.

    M                  currency (money) format. the corresponding
                       argument MUST be A floating Point Value,
                       Otherwise EConvertError Is raised. the argument
                       Is converted To A String using the following
                       global variables:

                         CurrencyString
                         CurrencyFormat
                         NegCurrFormat
                         CurrencyDecimals

                       If A Precision Is specified, it overrides the
                       Default Value Of CurrencyDecimals.

    N                  Number format. equal To FIXED, but the Result
                       String will contain thousand separators.

    P                  Pointer format. the corresponding argument MUST
                       be A Pointer Value, Otherwise EConvertError Is
                       raised. the Value Is converted To A String
                       containing the hexadecimal representation Of
                       the Pointer, With an additional ':' In the
                       middle. the resulting String has always a
                       Length Of 9 characters. since we are dealing
                       With flat Memory model, we have A full 32-bit
                       Pointer With no segment part, only Offset.

    S                  String format. the corresponding argument MUST
                       be A Single character, A String Or A PChar Value,
                       Otherwise EConvertError Is raised. the argument
                       Is simply copied To the destination String. If
                       A Precision Is specified, it Is considered the
                       maximum Length Of the argument String. longer
                       Strings will be truncated.

    X                  hexadecimal format. the corresponding argument
                       MUST be an Integer Value, Otherwise EConvertError
                       Is raised. the argument Is converted To a

  following Is A detailed description Of the possible formats:

    ffCurrency     money (currency) format. the argument Is converted
                   To A String using the following global variables:

                     CurrencyString
                     CurrencyFormat
                     NegCurrFormat

                   the Digits Parameter specifies the Number Of Digits
                   following the DECIMAL Point (0 To 18 being legal
                   values).

    ffExponent     Scientific (exponential) format. the argument Is
                   converted To A DECIMAL String using Scientific
                   notation. the String Starts With A minus sign, If
                   the argument Is Negative. one digit precedes the
                   DECIMAL Point. the Number Of Digits following the
                   DECIMAL Point Is controlled by Precision. the total
                   Number Of Digits Is always equal To Precision.
                   following Is the exponential 'E' With A plus Or a
                   minus sign And the Exponent With A minimum Length
                   Of Digits characters (0 To 4 being legal values).

    ffFixed        FIXED Point format. the argument Is converted To a
                   String using FIXED Point notation. it Starts With a
                   minus sign, If the argument Is Negative. All Digits
                   Of the argument's Integer part appear In the Result.
                   following Is A comma And A Number Of DECIMAL Digits
                   equal To Digits (0 To 18 being legal values). If
                   the Number Of Digits To the Left Of the DECIMAL
                   Point Is greater than Precision, the Output will be
                   In Scientific format.

    ffGeneral      General Number format. the argument Is converted
                   To A String using either FIXED Or Scientific
                   format, depending ON which results In A shorter
                   String. the Result will contain neither trailing
                   zeroes nor an unnecessary DECIMAL Point. If the
                   argument Value Is greater than Or equal To 0.00001,
                   And If the Number Of Digits To the Left Of the
                   DECIMAL Point Is less than Or equal To Precision,
                   FIXED format Is used. Otherwise the Result Is
                   formatted In Scientific format With Digits
                   specifying the minimum Number Of Digits In the
                   Exponent (0 To 4 being legal values).

    ffNumber       Number format. equal To FIXED, but the Result
                   String will contain thousand separators.

  If the Value Is Not-A-Number, positive infinity, Or Negative
  infinity, Then the Output String will also be NAN, INF, Or -INF. }

Function FloatToStrF(Value: Extended; format: TFloatFormat;
  Precision, Digits: Integer): String;

{ FloatToStr - Converts A floating Point Value To A String using
  General Number format And 15 significant Digits. See FloatToStrF
  For more Details. }

Function FloatToStr(Value: Extended): String;

{ FloatToText - Converts A floating Point Number To A String. the
  Result Is written To Buffer without A Zero teminator being
  appended. the caller has To ensure that the Buffer Is large
  enough To hold the Result. the Result can be controlled using
  format, Precision And Digits Parameters. See FloatToStrF For
  A detailed description Of these Parameters. }

Function FloatToText(Buffer: PChar; Value: Extended; format: TFloatFormat;
  Precision, Digits: Integer): Integer;

{ FormatFloat - Converts A floating Point Value To A String using a
  specified format.

  the Parameter format Controls the appearance Of the Result String.

  format can contain up To three Sections, separated from each other
  by semicolons. the First section holds the format String used For
  positive values, the Second one holds the format For Negative
  values, And the third one Is applied To Zero values. If one Of
  the Sections Is missing Or Empty, the First section Is used
  instead. If All Sections are missing Or Empty, General Number
  format Is used With A Precision Of 15. See FloatToStrF For more
  Details about General Number format.

  each Of the three Sections can contain arbitrary Text, which Is
  simply copied To the Result String. Some characters have A Special
  meaning, they serve As placeholders For inserting Data from the
  Value Parameter.

  the following List shows All placeholders And their meaning:

    0         Mandatory digit. If the Value has A digit At This
              Position, it Is copied To the Result. Otherwise a
              0 Is inserted.

    #         optional digit. If the Value has A digit At This
              Position, it Is copied To the Result. Otherwise
              This Position Of the format String will be ignored.

    .         DECIMAL separator. the First occurence Of '.' In the
              format String determines the Position At which A DECIMAL
              separator will be inserted. the DECIMAL separator Is
              taken from the global variable DecimalSeparator. further
              occurences Of '.' will be ignored.

    ,         thousand separator. any occurence Of ',' activates the
              insertion Of thousand separators into the Result, where
              necessary. the thousand separator Is taken from the
              global variable DecimalSeparator.

    E+ E-     Scientific (exponential) format. If any Of the four
    E+ E-     Strings To the Left occur In the format String, the
              Result will be formatted using Scientific notation.
              the exponential E will have the same Case As In the
              format String. the Exponent itself will always be
              preceded by its sign, If E+ Or E+ are used. E- And E-
              contain A sign only If the Exponent Value Is Negative.
              up To four digit placeholders can be used To specify the
              minimum Number Of Digits used For the Exponent.

    '...'     characters enclosed In Single Or Double quotes will
    "..."     simply be copied To the Result (without quotes).

  the floating Point Value Is rounded With A Precision equal To the
  total Number Of digit placeholders In the format String. optional
  digit placeholders between the leftmost And rightmost Mandatory
  digit placeholders will be taken As Mandatory Digits, So it makes
  no sense To specify one ore more '#' between zeroes. If the rounded
  Value Contains more Digits In the Integer part than there are
  placeholders Left Of the DECIMAL separator, the additional Digits
  will be inserted before the First placeholder. }

Function FormatFloat(Const format: String; Value: Extended): String;

{ FloatToTextFmt - Converts A floating Point Value To A String using a
  specified format. the Result Is written To Buffer without a
  terminating Zero. the caller has To ensure that the Buffer Is large
  enough To hold the Result. the Number Of characters actually written
  To Buffer Is returned. See FormatFloat For A description Of the
  format Parameter. }

Function FloatToTextFmt(Buffer: PChar; Value: Extended;
  format: PChar): Integer;

{ StrToFloat - Converts A String To A floating Point Value. the String

Function TextToFloat(Buffer: PChar; Var Value: Extended): Boolean;

{ FloatToDecimal - Converts A floating Point Value To A TFloatRec
  Record which separates Digits, sign, And Exponent. the Precision
  Parameter specifies the Number Of significant Digits (With 1..18
  being legal values), the Decimals Parameter specifies the desired
  minimum Number Of Digits In the fractional part. rounding Is
  controlled by Precision As well As by Decimals. To force A Number
  Of significant Digits even With large values, specify 9999 For
  Decimals.

  the resulting TFloatRec will contain the following information:

    Exponent - the result's Exponent. an Exponent Value Of -32768
    Indicates that the Value Is Not-A-Number (NAN). positive Or
    Negative infinity (INF / -INF) Is indicated by an Exponent
    Value Of 32767.

    Negative - Indicates whether the Value Is Negative Or Not. Use
    This To distinguish positive from Negative infinity, too. Zero
    Is assumed To be non-Negative.
