Several Binary-to-Decimal Libraries

I've put together a fairly extensive set of binary to decimal routines for the NES, each fairly thoroughly tested. There are three versions: tiny, standard, and fast. They all have a BSD-style license which has very few restrictions.

nes_bin2dec.zip

Their performance compares as follows:

The package includes demos that use each one and print the result on screen. There's also a thorough test for the 16-bit routines. They can be assembled directly with ca65 or NESASM. The fast version is based on the code Mozz posted. The standard version is based on Quietust's table version of Mozz's algorithm. The tiny version is based on Tepples' binary table code.

Post if you have any questions of problems using them.
