Rounds an floating point number to an integer.

round.js

var round = function (value) {
    // {value is some number}
    var multiplier = Math.abs(value) / value;
    var sValue = (value + (0.5 * multiplier)).toString();
    var point = sValue.indexOf(".");
    return parseInt(sValue.substring(0, point === -1 ? sValue.length : point), 10);
    // {returns value rounded}
};
