nearbyintf4

NAME

nearbyintf4 - return nearest integers to float elements ignoring floating point exceptions

SYNOPSIS

Procedure call syntax:

#include <simdmath.h>
vector float nearbyintf4(vector float x);
Link with -lsimdmath

Inline call syntax:

#include <simdmath.h>
#include <nearbyintf4.h>
vector float _nearbyintf4(vector float x);
Parameters  
x input vector

DESCRIPTION

The nearbyintf4 function returns a vector of the corresponding elements of x rounded to the nearest integer, consistent with the current rounding mode but without raising an inexact floating-point exception.

Special Case:
  • For the nearbyintf4 function on the SPU the rounding mode is always towards zero.

RETURN VALUE

The function nearbyintf4 returns a float vector in which each element is defined as the integer nearest to the corresponding element of x according to the current rounding mode.

ENVIRONMENT

SPU and PPU

CONFORMING TO

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

NOTES

Basis

ISO9899 (C99) nearbyint functions.
