This manual page is part of the POSIX Programmer's Manual. The Linux implementation of this interface may differ (consult the correspond- ing Linux manual page for details of Linux behavior), or the interface may not be implemented on Linux. NAME
cabs, cabsf, cabsl -- return a complex absolute value SYNOPSIS
#include <complex.h> double cabs(double complex z); float cabsf(float complex z); long double cabsl(long double complex z); DESCRIPTION
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.1-2008 defers to the ISO C standard. These functions shall compute the complex absolute value (also called norm, modulus, or magnitude) of z. RETURN VALUE
These functions shall return the complex absolute value. ERRORS
No errors are defined. The following sections are informative. EXAMPLES
None. APPLICATION USAGE
None. RATIONALE
None. FUTURE DIRECTIONS
