README
This directory was an experiment to use floating-point operations to implement the math library when a processor had a floating-point instruction set. The experiment was a failure in that some of the algorithms chosen (e.g. recursive algorithms for sin/cos, etc..) are too simple and do not provide proper accuracy nor handle very large or very small inputs adequately. The code is considered moth-balled. The stable math library routines can be found in libm/math and the configuration option to use this has been removed. If you wish to experiment with the concept, please feel free and report back if you have major improvements.
