Are there any plans to add a bignum class to Boost?
I tried to do this and submitted 2 versions so people could criticize it and always had to fight with people that demanded that the library has to be as fast as the fastest open source implementation (in this case, GMP.) I can not claim that speed, but I implemented a really fast big number library using assembler only on the critical paths on the most CPU demanding instructions. That was not enough for some boost-ers.
Could you point me to this library, please? I'ld like to try to put it into Wave to support cross compilation and/or configurable precision support.
IMO, you do not need an arbitrary precision integer. All you need is a fixed precision integer (64, 128 or 256 bits). That is a lot faster to operate on. There are lots of such libraries and it's easy to write one. Surely, you do not need to compute things like PI to a million decimal places ;-) Regards, -- Joel de Guzman http://www.boost-consulting.com http://spirit.sf.net
