Package Information

Description:
The "Numeric.FastMath" module brings into scope many unsafe @RULES@ for 'Float's and 'Double's 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 <http://github.com/liyang/fast-math/ README> on github for more details.
