Entering Large Amounts

The V12 displays numbers up to 10 digits. Scientific notation
allows numbers longer than 10 digits to be entered. To perform
this function, enter the number with the decimal point moved to
the left. Keep track of how many positions the decimal point
moved. Next touch the EEX button and enter the number of
positions the decimal point was moved. Touch the ENTER key
to complete the entry.
Example
To enter a value of 7,894,300,000,000 the decimal place should
move 12 spaces to the left leaving a mantissa of 7.8943 with an
exponent of 12.
