Number Entry and Display
Numbers are entered by pressing:
• Numbered keys, 0–9
• The decimal point .
•The } key
•The
:w keys
To correct a number entry, press the backspace key, {. Each press of { erases the last
digit or symbol you entered.
To enter a number in the display, press the number digits successively. A number can have up
to 12 digits.
To change the sign of a number from positive to negative, press }.
Use scientific notation to enter very large and very small numbers. For example, to enter the
number 1.23x 10
127
in scientific notation, first enter the mantissa (1.23) and then press
:w and enter the number (127) representing the exponent. The exponent must have a
value between –499 and +499. If an expression has more than 12 digits, or if an operation
returns a result with more than 12 digits, the calculator automatically displays scientific
notation.
