SysUtils.TryStrToCurr Function

Converts a string to a System::Currency value, with a Boolean success code.

function TryStrToCurr(const S: string; out Value: Currency): Boolean; overload;
function TryStrToCurr(const S: string; out Value: Currency; const FormatSettings: TFormatSettings): Boolean; overload;
Boolean TryStrToCurr(const AnsiString S, Currency Value);
Boolean TryStrToCurr(const AnsiString S, Currency Value, const TFormatSettings FormatSettings);

Call TryStrToCurr to convert a string that represents a floating-point value to the corresponding System::Currency value. The source string, S, must consist of an optional sign (+ or -), a string of digits with an optional decimal point, and an optional 'E' or 'e' followed by a signed integer. Leading and trailing blanks are ignored.  

The DecimalSeparator global variable or its TFormatSettings equivalent defines the character that is used as a decimal point. Thousand separators and currency symbols are not allowed in the string. If the string doesn't contain a valid value, TryStrToCurr returns Default. 

The first form of TryStrToCurr is not thread-safe, because it uses localization information contained in global variables. The second form of TryStrToCurr, which is thread-safe, refers to localization information contained in the FormatSettings parameter. Before calling the thread-safe form of TryStrToCurr, you must populate FormatSettings with localization information. To populate FormatSettings with a set of default locale values, call GetLocaleFormatSettings
