acoshf4

NAME

acoshf4 - return inverse hyperbolic cosines of float elements

SYNOPSIS

Procedure call syntax:

#include <simdmath.h>
vector float acoshf4(vector float x);
Link with -lsimdmath

Inline call syntax:

#include <simdmath.h>
#include <acoshf4.h>
vector float _acoshf4(vector float x);
Parameters  
x input vector

DESCRIPTION

The acoshf4 function returns the inverse hyperbolic cosines of the elements of x.

RETURN VALUE

The function acoshf4 returns a float vector in which each element is defined as acosh(x).

On the SPU element values of the result that are greater than HUGE_VALF are returned as HUGE_VALF and no error is reported.

ENVIRONMENT

SPU and PPU

CONFORMING TO

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

NOTES

Basis

ISO9899 (C99) acosh functions.
