ceild2

NAME

ceild2 - return ceilings of double elements

SYNOPSIS

Procedure call syntax:

#include <simdmath.h>
vector double ceild2(vector double x);
Link with -lsimdmath

Inline call syntax:

#include <simdmath.h>
#include <ceild2.h>
vector double _ceild2(vector double x);
Parameters  
x input vector

DESCRIPTION

The ceild2 function rounds the elements of the input vector upwards to the next integer value.

This function provides ceiling computation for the entire input range of IEEE floating point numbers. The ceiling of NaN values remain NaN, and the ceiling of subnormal values become zero.

RETURN VALUE

The function ceild2 returns a double vector in which each element is defined as the smallest integer value not less than x.

ENVIRONMENT

SPU only
