cabs() -- Mathematics Function (libm)

Complex absolute value function
#include <math.h>
double cabs(z) struct { double r, i; } z;

cabs() computes the absolute value,  or modulus, of its complex argument z.
The absolute value of a complex number is the length of the hypotenuse of a
right triangle whose  sides are given by the real  part r and the imaginary
part i.  The result is  the square root  of the sum  of the squares  of the
parts.
