> Test whether an unsigned integer is a power of 2.
## Usage
```javascript
var isPow2Uint32 = require( '@stdlib/math/base/assert/uint32-is-pow2' );
```
#### isPow2Uint32( x )
Tests whether `x` is a power of 2.
```javascript
var bool = isPow2Uint32( 2 );
// returns true
bool = isPow2Uint32( 5 );
// returns false
```
## Examples
```javascript
var isPow2Uint32 = require( '@stdlib/math/base/assert/uint32-is-pow2' );
var i;
for ( i = 0; i < 100; i++ ) {
console.log( 'isPow2( %d ) = %s', i, isPow2Uint32( i ) );
}
```
