Question

In Sencha Touch 2, how does one format a number with commas with either 0 or 2 decimal places? I imagine that there’s a built in way to do this?

For example, I have 1234.567 and I need the number as 1,234 and 1,234.57.

You can do it easily with JavaScript only :
Add commas to the number

function addCommas(nStr)
{
nStr += '';
x = nStr.split('.');
x1 = x[0];
x2 = x.length > 1 ? '.' + x[1] : '';
var rgx = /(\d+)(\d{3})/;
while (rgx.test(x1)) {
    x1 = x1.replace(rgx, '$1' + ',' + '$2');
}
return x1 + x2;
}

Round to the nearest integer

var result = Math.round(original) 

Round to two decimals

var result = Math.round(original*100)/100

Hope this helps
