OSS Library Calls (a - d) cabsl(3)
NAME
cabsl - Computes the long double complex absolute value
LIBRARY
H-series and J-series native Guardian processes: $SYSTEM.ZDLLnnn.ZCREDLL
32-bit H-series and J-series OSS processes: /G/system/zdllnnn/zcredll
64-bit H-series and J-series OSS processes: /G/system/zdllnnn/ycredll
SYNOPSIS
#include <complex.h>
long double cabsl(
long double complex z);
PARAMETERS
z Specifies a long double complex value.
DESCRIPTION
The cabsl() function is a long double complex version of the cabs( ) function; it takes a long
double complex argument and returns a long double complex result.
The cabsl() function computes the complex absolute value (also called norm, modulus, or mag-
nitude) of z.
NOTES
This function is implemented only for the IEEE_float floating-point option. Applications using
this function cannot be compiled if the specified floating-point option is Tandem_float.
RETURN VALUES
The cabsl() function returns the complex absolute value of its argument.
ERRORS
No errors are defined.
RELATED INFORMATION
Functions: cabs(3), cabsf(3), carg(3), fabs(3), hypot(3).
STANDARDS CONFORMANCE
This function conforms to the ISO/IEC 9899:1999 standard.
This function conforms to the IEEE Std 1003.1, 2004 Edition.
