unsigned | size |
A number manipulation class.
This is used to extract, convert, and manage simple numbers that are represented in C ascii strings in a very quick and optimal way. This class modifies the string representation each time the value is changed. No math expressions or explicit comparison operators are supported for the Numbers class because these are best done by casting to long first.
