Re: OT : Approximate / fast math libraries ?

Hi,

I have a number crunch application that is starting to hit bottlenecks in standard maths functions, like log, exp sqrt etc. Thing is, in many places I don't need much precision, so was wondering if there was anything I could do, like use a different library or enable some gcc options (currently using -O2) to speed things up.

gcc -ffast-math
?
