# isInteger
> Test if a value is a number having an integer value.
<section class="usage">
## Usage
```javascript
var isInteger = require( '@stdlib/assert/is-integer' );
```
#### isInteger( value )
Tests if a value is a `number` having an `integer` value.
<!-- eslint-disable no-new-wrappers -->
```javascript
var Number = require( '@stdlib/number/ctor' );
var bool = isInteger( 5.0 );
// returns true
bool = isInteger( new Number( 5.0 ) );
// returns true
bool = isInteger( -3.14 );
// returns false
bool = isInteger( null );
// returns false
```
#### isInteger.isPrimitive( value )
Tests if a `value` is a primitive `number` having an `integer` value.
<!-- eslint-disable no-new-wrappers -->
```javascript
var Number = require( '@stdlib/number/ctor' );
var bool = isInteger.isPrimitive( -3.0 );
// returns true
bool = isInteger.isPrimitive( new Number( -3.0 ) );
// returns false
```
#### isInteger.isObject( value )
Tests if a `value` is a `Number` object having an `integer` value.
<!-- eslint-disable no-new-wrappers -->
```javascript
var Number = require( '@stdlib/number/ctor' );
var bool = isInteger.isObject( 3.0 );
// returns false
bool = isInteger.isObject( new Number( 3.0 ) );
// returns true
```

## Examples
<!-- eslint-disable no-new-wrappers -->
<!-- eslint no-undef: "error" -->
```javascript
var Number = require( '@stdlib/number/ctor' );

var bool = isInteger( -5.0 );
// returns true
bool = isInteger( 0.0 );
// returns true
bool = isInteger( new Number( 5.0 ) );
// returns true
bool = isInteger( 5.256 );
// returns false
bool = isInteger( 1.0/0.0 );
// returns false
bool = isInteger( -1.0/0.0 );
// returns false
bool = isInteger( '5' );
// returns false
bool = isInteger( null );
// returns false
