We've added four new price-rounding options to make each type of operation explicit:
- Round to nearest multiple
- Round to nearest multiple (round up)
- Replace last digit(s)
- Replace last digit(s) (round up)
Previously, the 'Round whole number' option (still available for backwards compatibility) tried to cover two different behaviors. For example, when someone says "round to 9," they usually mean set the last digit to 9, but when they say "round to 5," they typically expect a multiple of 5.
These new options separate those behaviors clearly, so you can choose whether you want to round to a multiple or specifically replace the last digit(s) of a price.
