Readme

The Numeric.FastMath module brings into scope many unsafe RULES for Floats and Doubles that can greatly improve run time performance. It is roughly equivalent to gcc's -ffast-math compiler flag. Optimisation (at least -O1) must be enabled for any RULES to take effect.

These rules are unsafe because they don't strictly adhere to the IEEE-754 regulations and may subtly change the results of your numeric computations. See the README on github for more details.
