llroundf4

NAME

llroundf4 - return nearest integer values to float elements

SYNOPSIS

Procedure call syntax:

#include <simdmath.h>

llroundf4_t llroundf4(vector float x);

Link with -lsimdmath

Inline call syntax:

#include <simdmath.h>

#include <llroundf4.h>

llroundf4_t _llroundf4(vector float x);

Parameters
x	input vector

DESCRIPTION

The llroundf4 function returns a structure of vectors of signed long long integers which are nearest to the corresponding elements of x.

Special Cases:

Halfway values are rounded away from 0 (zero).
On the SPU the rounding mode is always towards 0 (zero).
If the rounded value is outside the range of the return type the numeric result is unspecified.

RETURN VALUE

The function llroundf4 returns a llroundf4_t structure containing vectors in which each element is defined as the nearest long long integer to the corresponding element of x.

The llroundf4_t structure is defined:

	typedef struct llroundf4_t {
	vector signed long long vll[2];
	} llroundf4_t;

ENVIRONMENT

SPU and PPU

CONFORMING TO

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