Data.Approximate.Numerics
Description
These functions provide wildly inaccurate but very fast approximations to common transcendental functions.
The algorithms here are based on Martin Ankerl's optimized pow,
http://martin.ankerl.com/2007/10/04/optimized-pow-approximation-for-java-and-c-c/
which is in turn based on
http://nic.schraudolph.org/pubs/Schraudolph99.pdf
