Normal display Scientific notation
When the answer exceeds the normal display capacity, it is automatically shown by
scientific notation, 10-digit mantissa and exponents of 10 up to 199.

lOverflow or error check
Overflow or error is indicated by the or sign and stops further calculations.
Overflow or error occurs: .
1) When an answer, whether intermediate or final, or accumulated total in the
independent memory is more than i x 10'°° ("E." sign appears).
2) When function calculations are performed with a number exceeding the input range
("E." sign appears).
3) When unreasonable operations are performed in statistical calculations ("E." sign
appears).
Ex.) You attempt to obtain 3? or on without any input data in = O).
4) When the total number of levels of explicitly and/or implicitly (with addition-
subtraction versus multiplication-division including x7 and x3) nested parentheses
exceeds six, or more than 18 pairs of parentheses are used. ("E." sign appears.)
Ex.) You have pressed the B key 18 times continuously before designating the
sequence of @939 .
To release these overflow checks:
i).2).3) . . . . . Press theEBkey.
4) ......... Press the E! key. Or press the key, and the intermediate result
just before the overflow occurs is displayed and the subsequent
calculation is possible.
