isinff4

NAME

isinff4 - verify if float elements are infinite

SYNOPSIS

Procedure call syntax:

#include <simdmath.h>
vector unsigned int isinff4(vector float x);
Link with -lsimdmath

Inline call syntax:

#include <simdmath.h>
#include <isinff4.h>
vector unsigned int _isinff4(vector float x);
Parameters  
x input vector

DESCRIPTION

The isinff4 function returns a vector in which each element indicates if the corresponding element of x is an infinity (positive or negative).

RETURN VALUE

On the SPU single-precision Inf values are not representable. Therefore the function isinff4 returns 0 for all input.

On the PPU the function isinff4 returns an unsigned int vector in which each element is defined as:
UINT_MAX if the element of x is either positive or negative infinity.
0 otherwise.

ENVIRONMENT

SPU and PPU

CONFORMING TO

SIMD Math library specification for the Cell Broadband Engineā„¢ Architecture.
