nfc puts a period even with no decimals

The function nfc() puts a period even when you set it to have no decimals. When you set it like this: nfc(num, 0) it still adds a period after the value. You could use the round() function as an alternative but it still seems weird.

Ok after testing this for a bit and being unable to reproduce the results. I figured it out, if you have something like nfc(10.1,0) it returns "10." rather than "10". of course if you put nfc(10.1,-1) it will return "10" but that's not a great feature. I'll look into the code and see if I can't trim the decimals with 0. I think we should raise an error when the second argument is negative or invalid.
