Readme
isEven
Test if a 32-bit integer is even.
Installation
npm install @stdlib/math-base-assert-int32-is-even
Usage
var isEven = require( '@stdlib/math-base-assert-int32-is-even' );
isEven( x )
Tests if 32-bit integer is even.
var bool = isEven( 5 );
// returns false
bool = isEven( -2 );
// returns true
bool = isEven( 0 );
// returns true
Examples
var randu = require( '@stdlib/random-base-randu' );
var round = require( '@stdlib/math-base-special-round' );
var isEven = require( '@stdlib/math-base-assert-int32-is-even' );
var bool;
var x;
var i;
for ( i = 0; i < 100; i++ ) {
x = round( randu()*100.0 );
bool = isEven( x );
console.log( '%d is %s', x, ( bool ) ? 'even' : 'not even' );
}
C APIs
Usage
#include "stdlib/math/base/assert/int32_is_even.h"
stdlib_base_int32_is_even( x )
Tests if 32-bit integer is even.
#include <stdbool.h>
bool out = stdlib_base_int32_is_even( -2 );
// returns true
out = stdlib_base_int32_is_even( 5 );
// returns false
The function accepts the following arguments:
- x:
[in] int32_t
input value.
bool stdlib_base_int32_is_even( const int32_t x );
Examples
#include "stdlib/math/base/assert/int32_is_even.h"
#include <stdio.h>
#include <stdbool.h>
#include <stdint.h>
int main( void ) {
const int32_t x[] = { 5, -5, 3, -3, 0, 2 };
bool b;
int i;
for ( i = 0; i < 5; i++ ) {
b = stdlib_base_int32_is_even( x[ i ] );
printf( "Value: %d. int32 Is even? %s.\n", x[ i ], ( b ) ? "True" : "False" );
}
}
