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.
Does anyone have any recommendations for fast maths ? search around on
the web I've found a lot of references to fast / approximate math
libraries, but nothing obvious.

line. There are also some libraries available from NASA that are public
