```javascript
var round = require( '@stdlib/math/base/special/round' );
```
#### round( x )
Rounds a `numeric` value to the nearest `integer`.
```javascript
var v = round( -4.2 );
// returns -4.0
v = round( -4.5 );
// returns -4.0
v = round( -4.6 );
// returns -5.0
v = round( 9.99999 );
// returns 10.0
v = round( 9.5 );
// returns 10.0
v = round( 9.2 );
// returns 9.0
v = round( 0.0 );
// returns 0.0
v = round( -0.0 );
// returns -0.0
v = round( Infinity );
// returns Infinity
v = round( -Infinity );
// returns -Infinity
v = round( NaN );
// returns NaN
