atanhf4

NAME

atanhf4 - return inverse hyperbolic tangents of float elements

SYNOPSIS

Procedure call syntax:

#include <simdmath.h>

vector float atanhf4(vector float x);

Link with -lsimdmath

Inline call syntax:

#include <simdmath.h>

#include <atanhf4.h>

vector float _atanhf4(vector float x);

Parameters
x	input vector

DESCRIPTION

The atanhf4 function returns the inverse hyperbolic tangents of the elements of x.

RETURN VALUE

The function atanhf4 returns a float vector in which each element is defined as atanh(x).

On the SPU, if the absolute value of xi is equal to 1, the corresponding element of the result is returned as HUGE_VALF, and if xi is equal to -1, the corresponding element of the result is returned as -HUGE_VALF. In either case, no error is reported.

ENVIRONMENT

SPU and PPU

CONFORMING TO

SIMD Math library specification for the Cell Broadband Engine™ Architecture.
