Round up final output in jquery

Question

I have the following code. Works beautifully apart from i want the final tinstotal variable to be rounded up to the nearest 1 (2.04 being rounded up to 3 etc)

$(document).ready(function(){

// Animate logo
$('#Logo').hide().fadeIn(800);

// Calculation Scripts
// Square Metres
var output = $('#SquareMetres'),
    tinoutput = $('#Tins'),
    priceoutput = $('#Price');
$('input[type="text"]').keyup(function() {
var width = parseFloat( $('#width').val()),
    height = parseFloat( $('#height').val()),
    result = height * width / 10000,
    finalresult = result.toFixed(2);
if (isNaN(result)) return;

output.text(finalresult);

// Tins
var tinmetres = 32.5,
    tinprice = 18.23,
    tinsresult = finalresult / tinmetres;
    tinstotal = tinsresult.toFixed(2);

tinoutput.text(tinstotal);

var price = tinstotal * tinprice,
    totalprice = price.toFixed(2);

priceoutput.text('£'+totalprice)

});
});

the script is active here at http://andyholmes.me/sitewizard/index.html in the red box near the bottom. Hope you guys can help, thanks!

Solution 1

tinstotal = Math.ceil(tinsresult);
tinoutput.text(tinstotal);

Math.ceil() will round to the next whole number

Solution 2

use javascript Math.round()

ex: 
var a = Math.round(2.60);
var b = Math.round(-2.60);
var c = Math.round(2.49);

Result : 
alert(a); => 3
alert(b); => -3
alert(c); => 2

Hope is helps you.

Solution 3

I would imagine you are looking for Math.ceil()

Math.ceil(7.004);
// expected output: 8

Math.ceil(-7.004);
// expected output: -7

Solution 4

priceoutput.text('£'+ Math.ceil(totalprice));

Solution 5

use javascript's Math.ceil() method to round numbers up.

You are already using Math.Ceil() So there is not point of using .toFixed(2)

This does not round up as requested. Your example clearly shows it rounds to nearest int.
