As part of some research, I was studying an implementation https://opensource.apple.com/source/Libm/Libm-315/Source/ARM/remquo.c which uses ideas which avoids the fixed point arithmetic. While there are some issues with this implementation, some of its ideas may produce cleaner and likely shorter code than the current remquo. maybe not so much with double but for anything else high, yes. Has anybody tried this before? Regards - Damian Pacific Engineering Systems International, 277-279 Broadway, Glebe NSW 2037 Ph:+61-2-8571-0847 ..
