How can I handle this string so that it returns only 2 decimals after the point?
$(".subtotal2").text(23.90);
var sum = 0;
$(".subtotal2").each(function() {
var val = $.trim( $(this).text() );
if (val) { val = parseFloat( val.replace( /^\$/, "" ) ); sum += !isNaN( val ) ? val : 0; }
});
$(".todo_total").text(sum*12);
This code for now returns this to me:
There are great answers about the subject in English OS .
You can even format your output using functions like:
toFixed(2);
toPrecision(12);
sprintf("%.2f", number);
round(number, 12);
However, as @mgibsonbr has commented, the best thing to do is to use integers.

$(".subtotal2").text((23.90).toFixed(2));
$(".todo_total").text((sum*12).toFixed(2));
