Round to exactly the precision you need

Enter any value and a precision from 0 to 12 places: 3.14159 at 2 places becomes 3.14, and at 0 places becomes 3. Standard rounding to the nearest applies — currency totals, lab measurements, and exam answers that demand a fixed format all come out tidy in one step.

Set 0 for whole numbers, 2 for paise-style money, more for measurements. Remember this rounds, never truncates: 2.5 goes up to 3 at zero places. Round only the final answer, never intermediate steps — early rounding is how spreadsheet totals drift by a rupee and lab readings lose a digit.

It applies standard rounding only — not truncation, round-half-even (banker's), or always-up billing rules — and caps precision at 12 places. Financial or legal rounding follows the policy your invoice or exam requires.
