NAME

roundd2 - return the nearest integer values to double elements

SYNOPSIS

Procedure call syntax:

#include <simdmath.h>
vector double roundd2(vector double x);
Link with -lsimdmath

Inline call syntax:

#include <simdmath.h>
#include <roundd2.h>
vector double _roundd2(vector double x);
Parameters  
x input vector

DESCRIPTION

The roundd2 function returns a vector which contains the corresponding elements of x rounded to the nearest integer.

Special Cases:
  • Halfway values are rounded away from 0 (zero), regardless of the current rounding direction
  • The rounding mode is always towards 0 (zero).

RETURN VALUE

The function roundd2 returns a double vector in which each element is defined as the nearest integer to the corresponding element of x.
