clogl(3) OSS Library Calls Reference Manual
NAME
clogl - Computes the long double complex natural logarithm function
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 complex clogl(
long double complex z);
PARAMETERS
z Specifies a long double complex value.
DESCRIPTION
The clogl( ) function is a long double complex version of the clog( ) function; it takes a long dou-
ble complex argument and returns a long double complex result.
The clogl( ) function computes the complex natural (base-e) logarithm of z, with a branch cut
along the negative real axis.
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 clogl( ) function returns the complex natural logarithm of z, in the range of a strip mathemati-
cally unbound along the real axis and in the interval [-iπ,+iπ] along the imaginary axis.
ERRORS
No errors are defined.
RELATED INFORMATION
Functions: cexp(3), clog(3), clogf(3), log(3).
STANDARDS CONFORMANCE
This function conforms to the ISO/IEC 9899:1999 standard.
This function conforms to the IEEE Std 1003.1, 2004 Edition.
