OSS Library Calls (a - d) cpowf(3)
NAME
cpowf - Computes the float complex power 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>
float complex cpowf(
float complex x,
float complex y
);
PARAMETERS
x Specifies a float complex value.
y Specifies a float complex value.
DESCRIPTION
The cpowf( ) function is a float complex version of the cpow( ) function; it takes float complex
arguments and returns a float complex result.
The cpowf( ) function computes the complex value of x raised to the power of y (or x
y
), with a
branch cut for the first parameter 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 cpowf( ) function returns the complex value of x raised to the power of y.
ERRORS
No errors are defined.
RELATED INFORMATION
Functions: cpow(3), cpowl(3), csqrt(3), pow(3).
STANDARDS CONFORMANCE
This function conforms to the ISO/IEC 9899:1999 standard.
This function conforms to the IEEE Std 1003.1, 2004 Edition.
