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 -2,147,483,648 to 2,147,483,647 (11 characters). The 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.
