     #include <complex.h>
     double cabs(double complex z);
     float cabsf(float complex z);
     

Description
These functions compute compute the complex absolute value (also called norm, modulus, or magnitude) of z.

cabsf is identical to cabs, except that it performs its calculations on floats complex.

Returns
The cabs functions return the complex absolute value.

Portability
