Hi, Here is the project page for a Real Time Fixed Point Math library. I had started writing this for fun and ended up submitting it as a mini-project last year but halted work on it sometime in November. There is a lot of scope for improvement and its not quite worth calling a 'Library' yet. Both the numerical algorithms used and their implementations can be improved. Many more functions could be added, besides the square root and trigonometric functions that are currently there. But even in its present state the code could be useful for those who require to do math on small micro-controllers. Those interested can check it out: Wiki http://gitorious.org/rtmath/pages/Home Project page: http://gitorious.org/rtmath/ -Nishchay -- ~~Jai Hind~~
