This function is recursive
It formats a number to a predefined number of decimal digits
It lDOES NOT round the number in case less decimal digits than those of the number are specified
It simply ignores digits beyond the specified number
i.e. Num = 1 and DecCount = 3 Result is 1,000
Num = 1,01235 and DecCount = 4 Result is 1,0123
It is therefore useful when one needs to add trailing zeroes to the decimal part of a number

Comma "," is used as decimal point; it can be changed to dot "."

It has been developed to send FileMaker data to a database that uses fixed length fields

Note: these functions are not guaranteed or supported by Please contact the individual developer with any questions or problems.
