About stdlib...

We believe in a future in which the web is a preferred environment for numerical computation. To help realize this future, we've built stdlib. stdlib is a standard library, with an emphasis on numerical and scientific computation, written in JavaScript (and C) for execution in browsers and in Node.js.

The library is fully decomposable, being architected in such a way that you can swap out and mix and match APIs and functionality to cater to your exact preferences and use cases.

When you use stdlib, you can be absolutely certain that you are using the most thorough, rigorous, well-written, studied, documented, tested, measured, and high-quality code out there.

To join us in bringing numerical computing to the web, get started by checking us out on GitHub, and please consider financially supporting stdlib. We greatly appreciate your continued support!

isEven

$NPM version$ $Build Status$ $Coverage Status$

Test if a finite numeric value is an even number.

Installation

1npm install @stdlib/math-base-assert-is-even

Usage

1var isEven = require( '@stdlib/math-base-assert-is-even' );

isEven( x )

Tests if a finite numeric value is an even number.

1var bool = isEven( 5.0 );
2// returns false
3
4bool = isEven( -2.0 );
5// returns true
6
7bool = isEven( 0.0 );
8// returns true
9
10bool = isEven( NaN );
11// returns false

Notes

The function assumes a finite number. If provided positive or negative infinity, the function will return true, when, in fact, the result is undefined. If x can be infinite, wrap the implementation as follows:

1function check( x ) {
2    return (
3        x < Infinity &&
4        x > -Infinity &&
5        isEven( x )
6    );
7}
8
9var bool = check( Infinity );
10// returns false
11
12bool = check( -Infinity );
13// returns false

Examples

1var randu = require( '@stdlib/random-base-randu' );
2var round = require( '@stdlib/math-base-special-round' );
3var isEven = require( '@stdlib/math-base-assert-is-even' );
4
5var bool;
6var x;
7var i;
8
9for ( i = 0; i < 100; i++ ) {
10    x = round( randu()*100.0 );
11    bool = isEven( x );
12    console.log( '%d is %s', x, ( bool ) ? 'even' : 'not even' );
13}

C APIs

Usage

1#include "stdlib/math/base/assert/is_even.h"

stdlib_base_is_even( x )

Tests if a finite numeric value is an even number.

1bool out = stdlib_base_is_even( 1.0 );
2// returns false
3
4out = stdlib_base_is_even( 4.0 );
5// returns true

The function accepts the following arguments:

x: [in] double input value.

1bool stdlib_base_is_even( const double x );

Examples

1#include "stdlib/math/base/assert/is_even.h"
2#include <stdio.h>
3#include <stdlib.h>
4#include <stdbool.h>
5
6int main( void ) {
7    double x;
8    bool v;
9    int i;
10    
11    for ( i = 0; i < 100; i++ ) {
12        x = ( ( (double)rand() / (double)RAND_MAX ) * 100.0 );
13        v = stdlib_base_is_even( x );
14        printf( "x = %lf, is_even(x) = %s\n", x, ( v ) ? "even" : "not even" );
15    }
16}
