Format Currency

Last updated on:

This function will round numbers to two decimal places, and ensure that the returned value has two decimal places. For example 12.006 will return 12.01, .3 will return 0.30, and 5 will return 5.00

function CurrencyFormatted(amount) {
	var i = parseFloat(amount);
	if(isNaN(i)) { i = 0.00; }
	var minus = '';
	if(i < 0) { minus = '-'; }
	i = Math.abs(i);
	i = parseInt((i + .005) * 100);
	i = i / 100;
	s = new String(i);
	if(s.indexOf('.') < 0) { s += '.00'; }
	if(s.indexOf('.') == (s.length - 2)) { s += '0'; }
	s = minus + s;
	return s;
}

  1. If you want a smaller function:

    
    function currency(N){N=parseFloat(N);if(!isNaN(N))N=N.toFixed(2);else N='0.00';return N;}
    
    // >> currency("-14"): "-14.00" 
    

    If you want a smaller, more inline alternative, you can do this:

    
    // Right after you declare your number (N), the rest of the line does the formatting.
    var N=24.686; N=parseFloat(N);if(!isNaN(N))N=N.toFixed(2);else N='0.00';
    // >> N: "24.69"
