//There are meny ways of rounding...
Math.floor(5.5) //Answer 5, it alwas rounds down.
Math.round(5.5) //Answer 6, it simpily rounds to the closest whole number.
Math.ceil(5.5) //Answer 6, it alwas rounds up.

//You can do more things too...
Math.floor(5.57 * 10) / 10 //Answer 5.5, the number turns into 55.7, Then gets floored (55.0), Then gets divied, (5.5).

var x = 5.0364342423;
console.log(x.toFixed(2));
