Well, with that result you're really asking for truncation, so I'll include that as an option.Number.prototype.round = function( places, truncate )
{
var factor = Math.pow( 10, places );
return Math[Boolean(truncate)?'floor':'round']( this * factor ) / factor;
}Then, the usagevar someNum = 25.3654;
var truncatedNum = someNum.round( 2, true );
var roundedNum = someNum.round( 2 );
