# isComposite
> Test if a number is a composite.
A **composite number** is defined as a positive integer value greater than `1` which has **at least** one divisor other than `1` and itself (i.e., an integer value which can be formed by multiplying two smaller positive integers).
## Usage
```javascript
var isComposite = require( '@stdlib/math/base/assert/is-composite' );
```
#### isComposite( x )
Tests if a number is a composite.
```javascript
var bool = isComposite( 4.0 );
// returns true
```
## Examples
```javascript
var isComposite = require( '@stdlib/math/base/assert/is-composite' );
var bool = isComposite( 4.0 );
// returns true
bool = isComposite( 7.0 );
// returns false
bool = isComposite( NaN );
// returns false
```
