NAME
cabs, cabsf, cabsl - absolute value of a complex number SYNOPSIS
#include <complex.h> double cabs(double complex z); float cabsf(float complex z); long double cabsl(long double complex z); Link with -lm. DESCRIPTION
These functions return the absolute value of the complex number z. The result is a real number. VERSIONS
These functions first appeared in glibc in version 2.1. ATTRIBUTES
