Error and Overflow Conditions and Indicators
If you divide by zero or calculate a selling price using a margin of 100%,
an error occurs. The calculator prints a row of dots and 0 .* and displays
E and 0.
An overflow occurs if you calculate a result with too many digits for the
calculator to display or print. When this occurs, the calculator:
• Prints a row of dots and the first 12 digits of the result with the
decimal shifted 12 places to the left of its correct position.
• Displays E and the first 12 digits of the result with a decimal point 12
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.
