uLisp creator David Johnson-Davies posted an infinite precision artithmetic package for uLisp.

One of the aims of the package was to keep it simple and understandable, so users could extend it with additional functions.

Curious that they used digits of 0-99 instead of 0-255. Simplicity perhaps?
@kirtai That's a possibility.
@amoroso THANK YOU! That is *most* useful at this moment!
