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

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

. The memory is not cleared
unless the error or overflow occurred in a memory calculation.
