> Test if a 32-bit integer is odd.
## Usage
```javascript
var isOdd = require( '@stdlib/math/base/assert/int32-is-odd' );
```
#### isOdd( x )
Tests if 32-bit integer is odd.
```javascript
var bool = isOdd( 5 );
// returns true
bool = isOdd( -2 );
// returns false
bool = isOdd( 0 );
// returns false
```
## Examples
```javascript
var randu = require( '@stdlib/random/base/randu' );
var round = require( '@stdlib/math/base/special/round' );
var isOdd = require( '@stdlib/math/base/assert/int32-is-odd' );
var bool;
var x;
var i;
for ( i = 0; i < 100; i++ ) {
x = round( randu()*100.0 );
bool = isOdd( x );
console.log( '%d is %s', x, ( bool ) ? 'odd' : 'not odd' );
}
```
