Frequently asked questions
What happens exactly halfway between two values?
Standard rounding rounds halfway values up — 2.5 rounds to 3, and 0.45 rounded to one decimal place rounds to 0.5, not down to 0.4.
What's a real use for 'round to nearest multiple'?
Pricing in round increments (nearest $5 or $0.25), scheduling in time blocks (nearest 15 minutes), or any context where values need to land on specific steps rather than any decimal value.
