Rounding Calculator
Round a value to decimal places using ties away from zero.
Your numbers
Rounded value
Use consistent units. The result follows the assumptions you enter.
Scenario comparison
Up to three snapshots in this tab. Loading one replaces the current inputs.
Formula
Use R = sign(x)round(abs(x)×10^p)/10^p. x is the value and p is decimal places. abs means absolute value; sign restores the sign. Halfway cases round away from zero; negative places round to larger place values.

Scope and limitations
Use consistent units. The result follows the assumptions you enter.
Inputs are checked for missing values and allowed ranges. A result outside the finite numeric range is not displayed. Rounding affects display, while the calculation uses the model’s numeric precision.
Check your units and assumptions before relying on a result. Changing a label does not convert a currency or physical unit.
