PROLOG top

       This manual page is part of the POSIX Programmer's Manual.  The       Linux implementation of this interface may differ (consult the       corresponding Linux manual page for details of Linux behavior), or       the interface may not be implemented on Linux.

NAME top

       cabs, cabsf, cabsl — return a complex absolute value

SYNOPSIS top

       #include <complex.h>       double cabs(double complexz);       float cabsf(float complexz);       long double cabsl(long double complexz);

DESCRIPTION top

       The functionality described on this reference page is aligned with       the ISO C standard. Any conflict between the requirements       described here and the ISO C standard is unintentional. This       volume of POSIX.1‐2017 defers to the ISO C standard.       These functions shall compute the complex absolute value (also       called norm, modulus, or magnitude) ofz.

RETURN VALUE top

       These functions shall return the complex absolute value.
