# isInfinite
> Test if a value is an infinite number.
## Usage
```javascript
var isInfinite = require( '@stdlib/assert/is-infinite' );
```
#### isInfinite( value )
Tests if a value is an infinite `number`.
```javascript
var Number = require( '@stdlib/number/ctor' );
var bool = isInfinite( 1.0/0.0 );
// returns true
bool = isInfinite( new Number( 1.0/0.0 ) );
// returns true
bool = isInfinite( 1.0 );
// returns false
bool = isInfinite( null );
// returns false
```
#### isInfinite.isPrimitive( value )
Tests if a `value` is a primitive `number` having an infinite value.
```javascript
var Number = require( '@stdlib/number/ctor' );
var bool = isInfinite.isPrimitive( -1.0/0.0 );
// returns true
bool = isInfinite.isPrimitive( new Number( -1.0/0.0 ) );
// returns false
```
#### isInfinite.isObject( value )
Tests if a `value` is a `Number` object having an infinite value.
```javascript
var Number = require( '@stdlib/number/ctor' );
var bool = isInfinite.isObject( 1.0/0.0 );
// returns false
bool = isInfinite.isObject( new Number( 1.0/0.0 ) );
// returns true
```
## Examples
```javascript
var Number = require( '@stdlib/number/ctor' );
var isInfinite = require( '@stdlib/assert/is-infinite' );
var bool = isInfinite( 1.0/0.0 );
// returns true
bool = isInfinite( -1.0/0.0 );
// returns true
bool = isInfinite( new Number( 1.0/0.0 ) );
// returns true
bool = isInfinite( -5.0 );
// returns false
bool = isInfinite( 0.0 );
// returns false
bool = isInfinite( 5.256 );
// returns false
bool = isInfinite( '1.0/0.0' );
// returns false
bool = isInfinite( null );
// returns false
```
