2 function FormatCurr ( const Formatting : string; Value : Currency; FormatSettings : TFormatSettings ) : string;
Description
The FormatCurr function provides rich Formatting of a currency Value into a string.
The Formatting string may contain a mix of freeform text and control characters:
0 : Forces digit display or 0
# : Optional digit display
, : Forces display of thousands
. : Forces display of decimals
E+ : Forces signed exponent display
E- : Optional sign exponent display
; : Separator of +ve -ve and zero values
These are best understood by looking at the sample code.
Version 2 of this function is for use within threads. You furnish the FormatSettings record before invoking the call. It takes a local copy of global formatting variables that make the routine thread safe.
