Re: Problem With Math.h

Well my first comment (question actually) would be, why could you possibly need asin()??? I'm assuming this is for range estimation, in which case atan() makes more sense, to me at least.

Secondly, CORDIC can by design do asin() - you need to slightly modify the code to get it to work, however.

Use the identity:
asin(x) = atan(x/sqrt(1-x*x))
