Treebeard's String-Math

[James D Jarvis]

I put this together a few years back for +-?* strimg math routines.

What I didn't include was a way to carry repeating decimals (repetends). So 1 / 3 * 3 will result in .9... instead of 1, just as .3... * 3 would result in .9...

So I would consider it unfinished for use in a calculator.

still interesting, thanks for sharing. I'm using right shifting and left shifting to handle division and multiplication as much as possible, just using base 10 instead of binary. My code still is buggy and not clean enough to share yet.
