Round NUM to the nearest TPLACE.

ROUNDED

Because we want to round to the plural_form(TPLACE, 2) place, we need to look at the digit in the TPLACES place.

The digit in the TPLACES place is KEYDIGIT.

Because KEYDIGIT is more than 5, we round up to ROUNDED.

Because the TPLACES place digit is KEYDIGIT, we round up to ROUNDED.

Because KEYDIGIT is less than 5, we round down to ROUNDED.
