Math.round() and Math.floor() problem with setInterval()

Question

I'm having problem with Math.round() and Math.floor() in setInterval() function by using jQuery.

This is my code:

var number1 = 400;
var up_up = setInterval(
function (){
    number1 = parseFloat(number1) + parseFloat(0.2548777);
    number1 = Math.round(number1);
    $('#number1').html(number1);
}, 1000);

The Math.round() or Math.floor() doesn't work, but when I use Math.ceil() it works fine, but I want round or floor..

Please help

When you say 'doesn't work' you mean always rounds down and keeps the value of number1 at 400 indefinitely. You need to save the rounded value to a different variable or assign it directly to your display field. :)
