Hi

I was trying to compile some source codebut it requires the use of a function log2(). I can only find log() and log10(). If anybody knows where it is how how to do log2 of a variable i would reaaly appreciate any help.

Thanks

OOooooh, basic math *grin*. Remember kids,

loga(b) equals logc(b)/logc(a) for any c.

(kinda easy to proof, to).

so just do a log(x)/log(2) and you should be fine, wether you use the 10-log or the natural log.
