Entering Numbers

You can enter numbers in scientific notation regardless of which display format you have selected.


Procedure

To enter numbers in scientific notation:
  1. Enter the mantissa, including [ +/- ] if negative.
  2. Press [ EE ]
  3. Enter the exponent, including [ +/- ] if negative.
When you press an operation key, the display and resulting notation depend on prior conditions.
  • If you have previously selected standard or scientific notation, the number is displayed in the scientific format and the calculator remains in scientific notation until changed.
  • If you have previously selected engineering notation, the number is normalized to the engineering format and the calculator remains in engineering notation until changed.

Example

Enter the number -74.07 × 10⁴ when the calculator is in the standard display format.
