# isPositiveZero
> Test if a value is a number equal to positive zero.
## Usage
```javascript
var isPositiveZero = require( '@stdlib/assert/is-positive-zero' );
```
#### isPositiveZero( value )
Tests if a `value` is a `number` having a value equal to positive zero.
```javascript
var Number = require( '@stdlib/number/ctor' );
var bool = isPositiveZero( 0.0 );
// returns true
bool = isPositiveZero( new Number( 0.0 ) );
// returns true
bool = isPositiveZero( -3.14 );
// returns false
bool = isPositiveZero( -0.0 );
// returns false
bool = isPositiveZero( null );
// returns false
```
#### isPositiveZero.isPrimitive( value )
Tests if a `value` is a primitive `number` equal to positive zero.
```javascript
var Number = require( '@stdlib/number/ctor' );
var bool = isPositiveZero.isPrimitive( 0.0 );
// returns true
bool = isPositiveZero.isPrimitive( new Number( 0.0 ) );
// returns false
```
#### isPositiveZero.isObject( value )
Tests if a `value` is a `Number` object having a value equal to positive zero.
```javascript
var Number = require( '@stdlib/number/ctor' );
var bool = isPositiveZero.isObject( 0.0 );
// returns false
bool = isPositiveZero.isObject( new Number( 0.0 ) );
// returns true
```
## Examples
```javascript
var Number = require( '@stdlib/number/ctor' );
var isPositiveZero = require( '@stdlib/assert/is-positive-zero' );
var bool = isPositiveZero( 0.0 );
// returns true
bool = isPositiveZero( new Number( 0.0 ) );
// returns true
bool = isPositiveZero( -3.14 );
// returns false
bool = isPositiveZero( -0.0 );
// returns false
bool = isPositiveZero( 5.0 );
// returns false
bool = isPositiveZero( '0' );
// returns false
bool = isPositiveZero( null );
// returns false
```
