okay, (on linux) you find math.h in /usr/include/ which includes a file /usr/include/bits/mathcalls.h there are three functions int finite(double x) -- returns 1, if x is not NaN or inf int isinf(double x) -- returns 1, if x is inf or -inf int isnan(double x) -- returns 1, if x is NaN
int finitef(float x), int isnanf(float x), and int isinff(float x) are the float versions.
