Total fields and add 2 decimal places only if fields have decimals?

Question

Currently, I have the function:

function TotalAmount(field, container) {
    var total = 0;
    field.each(function () {
        total += $(this).val() * 1;
    });
    container.val(total.toFixed(2));
}

Example(1):
55.00 + 50.00 = 105.00 (this is correct)

Example (2):
This currently returns:
55 + 50 = 105.00

I need it to return 105 instead.

How do I change my functionality to accomplish this?

Try

function TotalAmount(field, container) {
    var total = 0;
    field.each(function () {
        total += $(this).val() * 1;
    });
    container.val(total == parseInt(total) ? total : total.toFixed(2));
}

Demo: Fiddle

for fiedl1: 1.00, field2: 1.00 and field3: 1.00, I get 3 instead of 3.00 – Chaka Sep 09 '13 at 15:18
@Chaka that is what you wanted right? `55 + 50 = 105` not `105.00` – Arun P Johny Sep 09 '13 at 15:30

Using modulous operator can solve ur issue:

If (total % 1 != 0)
return total
else 
return total / 100
