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
Æ
0 ].
(Ex.) : Correct 12385 as 789
DEG
Step: Press [ CE ] 789
7 8 9.
(Ex.) : Correct 12385 as 123
DEG
Step: Press [ 00
Æ
0 ] twice
1 2 3.
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 :
±
1 in 10th digit.
Capacity :
In general, every reasonable calculation is displayed up to 10 digit
mantissa, or 10-digit mantissa plus 2-digit exponent up to 10
±
99
or
integers 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
following pages.
