#### fromBinaryStringUint32( bstr )
|
||
|
|
|
||
|
|
Creates an unsigned 32-bit integer from a [literal bit representation][@stdlib/number/uint32/base/to-binary-string].
|
||
|
|
|
||
|
|
```javascript
|
||
|
|
var bstr = '01010101010101010101010101010101';
|
||
|
|
var val = fromBinaryStringUint32( bstr );
|
||
|
|
// returns 1431655765
|
||
|
|
|
||
|
|
bstr = '00000000000000000000000000000000';
