The calculator rounds the result and displays it as 1. This rounding enables the
calculator to display the most accurate result.
Although most calculations are accurate to within ±1 in the last displayed digit,
higher-order mathematical functions use iterative calculations, in which
inaccuracies can accumulate in the guard digits. In most cases, the cumulative
error from these calculations is maintained beyond the 10-digit display so that
no inaccuracy is shown.
AOS™ (Algebraic Operating System) Calculations
When you select the AOS calculation method, the calculator uses the standard
rules of algebraic hierarchy to determine the order in which it performs
operations.

Battery Information
Replacing the Battery
Replace the battery with a new CR2032 lithium battery.
Caution: The calculator cannot retain data when the battery is removed or
discharged. Replacing the battery has the same effect as resetting the
calculator.
