Use
The purpose of this call is to convert a value into an unsigned string of decimal characters.
Notes
The output can be a value from 0 to 16,777,215. The commas are not output.
The string is not padded with zeros, so is of variable length.
Every three digits from the right, a space is inserted. e.g. 16 777 215.
