## Usage
|
||
|
|
|
||
|
|
```javascript
|
||
|
|
var uint32ToInt32 = require( '@stdlib/number/uint32/base/to-int32' );
|
||
|
|
```
|
||
|
|
|
||
|
|
#### uint32ToInt32( x )
|
||
|
|
|
||
|
|
Converts an unsigned 32-bit integer to a signed 32-bit integer.
|
||
|
|
|
||
|
|
```javascript
|
||
|
|
var float64ToUint32 = require( '@stdlib/number/float64/base/to-uint32' );
|
||
|
|
|
||
|
|
var y = uint32ToInt32( float64ToUint32( 4294967295 ) );
|
||
|
|
// returns -1
|
||
|
|
|
||
|
|
y = uint32ToInt32( float64ToUint32( 3 ) );
|
||
|
|
// returns 3
|
||
|
|
```
