## 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
|
||
|
|
```
