Rounding (ROUND Switch) 9 5/4 : Results are rounded up (if DECIMAL = 1, 2. 33 rounds to 2. 4). Results are rounded up or down, depending on the value and decimal setting (if DECIMAL = 2, 2. 349 rounds to 2. 35). Results are rounded down (if DECIMAL = 1, 2. 33 rounds to 2. 3). Using Decimals (DECIMAL Switch) + X F 0, 2, 3, 4, 6 Lets you add and subtract numbers without entering the decimal point (key in 5321 to enter 53. 21). Lets you multiply and divide numbers without entering the decimal point (key in 3 x 250 = to enter 3 x 2. 50 = 7. 50). The number of decimal places varies based on the result. Sets the number of decimal places to 0, 2, 3, 4, or 6. 3 Clearing Errors and Overflows Correcting Entry Errors If you have not pressed an operation key: · To clear an incorrect entry, press I. · To clear the last digit, press (.

An overflow occurs if you calculate a result with too many digits for the calculator to display or print. When this occurs, the calculator: · Displays E and the first 12 digits of the result with a decimal point 11 places to the left of its correct position. · Prints ERROR and the first 12 digits of the result with the decimal shifted 11 places to the left of its correct position. To clear an error or overflow, press 2. The memory is not cleared unless the error or overflow occurred in a memory calculation.
