cabs, cabsf, cabsl - absolute value of a complex number
double cabs(double complex z);
float cabsf(float complex z);
long double cabsl(long double complex z);
Link with -lm.
The cabs() function returns the absolute value of the complex number z.
The result is a real number.
The function is actually an alias for hypot(a, b) (or, equivalently,
sqrt(a*a + b*b)).
