# isOdd
> Test if a value is an odd number.
## Usage
```javascript
var isOdd = require( '@stdlib/assert/is-odd' );
```
#### isOdd( value )
Tests if a `value` is an odd `number`.
```javascript
var Number = require( '@stdlib/number/ctor' );
var bool = isOdd( 5.0 );
// returns true
bool = isOdd( new Number( 5.0 ) );
// returns true
bool = isOdd( 6.0 );
// returns false
bool = isOdd( -3.14 );
// returns false
bool = isOdd( null );
// returns false
bool = isOdd( NaN );
// returns false
```
#### isOdd.isPrimitive( value )
Tests if a `value` is an odd primitive number.
```javascript
var Number = require( '@stdlib/number/ctor' );
var bool = isOdd.isPrimitive( -5.0 );
// returns true
bool = isOdd.isPrimitive( new Number( -5.0 ) );
// returns false
```
#### isOdd.isObject( value )
Tests if a `value` is a `Number` object having an odd number value.
```javascript
var Number = require( '@stdlib/number/ctor' );
var bool = isOdd.isObject( 5.0 );
// returns false
bool = isOdd.isObject( new Number( 5.0 ) );
// returns true
```
## Examples
```javascript
var Number = require( '@stdlib/number/ctor' );
var isOdd = require( '@stdlib/assert/is-odd' );
var bool = isOdd( 5.0 );
// returns true
bool = isOdd( new Number( 5 ) );
// returns true
bool = isOdd( 0.0 );
// returns false
bool = isOdd( 4.0 );
// returns false
bool = isOdd( NaN );
// returns false
bool = isOdd( '5' );
// returns false
bool = isOdd( null );
// returns false
```
