# isEven
> Test if a value is an even number.
## Usage
```javascript
var isEven = require( '@stdlib/assert/is-even' );
```
#### isEven( value )
Tests if a `value` is an even `number`.
```javascript
var Number = require( '@stdlib/number/ctor' );
var bool = isEven( 6.0 );
// returns true
bool = isEven( new Number( 6.0 ) );
// returns true
bool = isEven( 3.0 );
// returns false
bool = isEven( -3.14 );
// returns false
bool = isEven( null );
// returns false
bool = isEven( NaN );
// returns false
```
#### isEven.isPrimitive( value )
Tests if a `value` is a primitive even `number`.
```javascript
var Number = require( '@stdlib/number/ctor' );
var bool = isEven.isPrimitive( -4.0 );
// returns true
bool = isEven.isPrimitive( new Number( -4.0 ) );
// returns false
```
#### isEven.isObject( value )
Tests if a `value` is a `Number` object having an even number value.
```javascript
var Number = require( '@stdlib/number/ctor' );
var bool = isEven.isObject( 4.0 );
// returns false
bool = isEven.isObject( new Number( 4.0 ) );
// returns true
```
## Examples
```javascript
var Number = require( '@stdlib/number/ctor' );
var isEven = require( '@stdlib/assert/is-even' );
var bool = isEven( 4.0 );
// returns true
bool = isEven( 0.0 );
// returns true
bool = isEven( new Number( 4 ) );
// returns true
bool = isEven( 5.0 );
// returns false
bool = isEven( NaN );
// returns false
bool = isEven( '5' );
// returns false
bool = isEven( null );
// returns false
```
