How to use the Rounding Calculator

Enter the number you want to round. Choose nearest whole, tenth, hundredth, thousandth, a custom number of decimal places, or significant figures.

The calculator uses standard half-up rounding for positive numbers (5 and above rounds away from zero at that place) and shows both the rounded value and which digit decided the round.
