Correction

If you have made a mistake when entering a number (but you have not yet
pressed an arithmetic operator key), just press [ CE ] to clear the last entry
then input it again, or delete individual digits by using the backspace key
[ 00 0 ]
(Ex.) : Correct 12385 as 789
Step : press [ CE ] 789
(Ex.) : Correct 12385 as 123
Step : press [ 00 0 ] twice
In a series of calculations, you can correct errors in immediate results
by pressing [ON/C] to clear the calculation completely (expect clearing
memory, see page 9).
If you press the wrong arithmetic operation key, just press [ CE ] key
before entering anything else.

Accuracy and Capacity

Accuracy :
Capacity :
In general, every reasonable calculation is displayed up to 10 digit
mantissa, or 10-digit mantissa plus 2-digit exponent up to 10
between – 9999999999 and 9999999999.
Numbers used as input must be within the range of the given
function. The range for each of the calculator's functions is given in the
