Description

Computes the is_negative:

Parameters

i1_first, i1_last

The range of input elements

o0

The beginning of the destination range, may be equal to i1

i1

The scalar/contiguous data input element

Example


#include <time.h>
#include <stdio.h>
#include <stdlib.h>
#include <stdint.h>
#include <stddef.h>
#include <archr/core/is_negative.h>

  return min + ((double)(max - min) * ((double)rand() / RAND_MAX));
}

  size_t i;
  size_t sz = 10;
  int32_t* i1 = (int32_t*)malloc(sz * sizeof(int32_t));
  uint32_t* o1 = (uint32_t*)malloc(sz * sizeof(uint32_t));

  for (i = 0; i < sz; ++i) {

  for (i = 0; i < sz; ++i) {
