# isComposite
> Test if a value is a composite number.
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/assert/is-composite' );
```
#### isComposite( value )
Tests if a `value` is a composite number.
```javascript
var Number = require( '@stdlib/number/ctor' );
var bool = isComposite( 4.0 );
// returns true
bool = isComposite( new Number( 4.0 ) );
// returns true
bool = isComposite( 3.14 );
// returns false
bool = isComposite( -4.0 );
// returns false
bool = isComposite( NaN );
// returns false
bool = isComposite( null );
// returns false
```
#### isComposite.isPrimitive( value )
Tests if a `value` is a primitive composite number.
```javascript
var Number = require( '@stdlib/number/ctor' );
var bool = isComposite.isPrimitive( 4.0 );
// returns true
bool = isComposite.isPrimitive( new Number( 4.0 ) );
// returns false
```
#### isComposite.isObject( value )
Tests if a `value` is a `Number` object having a value which is a composite number.
```javascript
var Number = require( '@stdlib/number/ctor' );
var bool = isComposite.isObject( 4.0 );
// returns false
bool = isComposite.isObject( new Number( 4.0 ) );
// returns true
```
## Examples
```javascript
var Number = require( '@stdlib/number/ctor' );
var isComposite = require( '@stdlib/assert/is-composite' );
var bool = isComposite( 4.0 );
// returns true
bool = isComposite( new Number( 4.0 ) );
// returns true
bool = isComposite( 10.0 );
// returns true
bool = isComposite( 7.0 );
// returns false
bool = isComposite( 3.14 );
// returns false
bool = isComposite( -4.0 );
// returns false
bool = isComposite( NaN );
// returns false
bool = isComposite( '0.5' );
// returns false
bool = isComposite( null );
// returns false
```
