RxUtilEx - Sys2FormatNumber

Formats a number to use thousands-grouping characters. The system values for the current locale are used for the thousands-grouping character and the decimal place, if any. Note that the IBM C runtime's built-in locale definitions are used; these may not correspond precisely to the system locales as defined in the OS/2 Locale object.

The input number may be a positive or negative integer or floating point value. It must be a simple, non-localized number value; in other words, it must not contain any thousands-grouping characters, and any decimal point which it contains must be a period (rather than any localized decimal symbol).

Arguments
REXX ARGUMENTS: 1. Number to be formatted. (REQUIRED) 2. Number of decimal places to use for floating point values. Ignored for integer values. (DEFAULT: 2) REXX RETURN VALUE: The formatted number, or '' on error.
