Overflow ~ Underflow
When the result of a calculation is larger than 14 digits, the figure is

than scientific notation's upward limit (E 125), an overflow occurs. The
display shows all 9's and E 126. This means you have exceeded the
display capabilities of the calculator. Clear the entry to correct this
condition.
Conversely, If the result of a calculation is so small that all thirteen
digits on the display are zero, the figure is displayed using scientific
nota tion. If the number is even less than scienti f ic nota tion can
display (E -127), an underflow occurs. The display then shows all 9's and
E 126. This means you have exceeded the display capabilities of the
calculator. Clear the entry to correct this condition.
