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?

Answer 1

Try

 container.val(total == parseInt(total) ? total : total.toFixed(2));

parseInt

Answer 2

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

Answer 3

Using modulous operator can solve ur issue:

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