Of course, platform availability. Have a look on this algo. Fun guaranteed!

Floats are already at the edge in our IQ correction algorithm (120+ dB image rejection). With fast-math, there will be a numerical stability problem in special signal conditions. I use fast-math elsewhere where it's really needed.

Interesting. I will definitly take a look at that.

By the way, what's the reason you have "re-implemented" complex arithmatic? Is complex.h not availble on some platforms you target or did you experience some other problem?
