Range off Numbers and OVERFLOW
The smallest magnitude of a number available on the calculator is
1x 10"499. The largest magnitude is 9.99999999999 x 10499 (dis
played as 1.0000E590 because of rounding).
• If a calculation produces a result that exceeds the largest possible
magnitude, then the number 9.99999999999 x 10499 is provided in
stead. The warning message OVERFLOW appears.
• If a calculationproduces a result smaller than the smallest possible
magnitude, then zero is provided instead. There is no warning.
Doing Arithmetic
When you press a function key, the calculator immediately executes
the function written on that key. Therefore, all operands (numbers)
must be present before you press the function key.
All calculations can be broken down into one-number functions and
two-number functions.
One-Number Functions
To use a one-number function (such as 11/xI, [W\, mfxH/ and P£l):
1. Key in the number. (You do not need to press I enter I.)
2. Press the function key. (Fora shifted function, press the shift key
first.)
For example, calculate 1/32 and V148.84 . Then square the last result
and change its sign.
