TinyMUX supports 64-bit numbers on both 32-bit and 64-bit platforms. TinyMUSH and RhostMUSH support the native integer size (32-bit or 64-bit depending on the platform) with the caveat that RhostMUSH does not compile on 64-bit platforms.

On PennMUSH, inc() does not perform simple addition. Instead, it adds 1 to the last string of digits present in its argument. This means that inc(hi2) => hi3, but also means that inc(1.3) => 1.4, which may be surprising. Use add() for true addition.
