Round

Round a numeric value to the nearest integer.

Usage

var round = require( '@stdlib/math/base/special/round' );

round( x )

Rounds a numeric value to the nearest integer.

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

Notes

Ties are rounded toward positive infinity.

Examples

var randu = require( '@stdlib/random/base/randu' );
var round = require( '@stdlib/math/base/special/round' );

var x;
var i;

for ( i = 0; i < 100; i++ ) {
    x = (randu()*100.0) - 50.0;
    console.log( 'Value: %d. Rounded: %d.', x, round( x ) );
}
