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
DEG
789.
(Ex.) : Correct 12385 as 123
Step : press [ 00
→
0 ] twice
DEG
123.
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.
