Use
The purpose of this call is to convert a value into a signed string of decimal characters.
Notes
The output can be a value from -8,388,608 to 8,388,607 (10 characters). Commas are not output.
If the most significant bit is set (of the number bytes used), the number is taken to be negative, and a leading ‘–’ is produced.
The string is not padded with zeros, so is of variable length.
Every three digits from the right, a space is inserted. e.g. 8 388 608
