Benchmark for DWORD to ASCII algorithms

[hutch--]

The attached file has a benchmark to test a collection of conversion algorithms. The result for the test is written to BMLOG.TXT.

These are the results on my dev Core2 quad.

rsrc.rc, line 21 might require a tiny change:

chokes on some puters: #include "H:/masm32/INCLUDE/resource.h"
heals the problem: #include "/masm32/INCLUDE/resource.h"

  Yep.

which ever algo you choose, 4294967296 possible values isn't too many to do a complete functional test
(i.e., verify correct output strings for 4294967296 cases)   

sometimes the fastest algo is fast because it isn't doing what it's supposed to - lol

[hutch--]

Everybody has a theory,the algo do as the algos do. From memory I tested all of them over the DWORD range and all are correct.
