Scientific Notation

Scientific notation is used to represent numbers that are too large or too small to fit in the display. For example, if you enter the number 10,000,000 x 10,000,000 =, the result is 1.00E14, which means one times ten to the fourteenth power, or 1.00 with the decimal point

moved fourteen places to the right. You can enter this number by pressing J\ zJY. The E stands for exponent of ten.

Exponents can also be negative for very small numbers. The number 0.000000000004 is displayed as 4.00E–12, which means four times ten to the negative twelfth power, or 4.0 with the decimal point moved 12 places to the left. You can enter this number by pressing

Y\zyJG.

Interchanging the Period and Comma

To switch between the period and comma (United States and International display) used as the decimal point and digit separator, press \8.

For example, one million can be displayed as 1,000,000.00 or 1.000.000,00. Pressing \8, toggles between these options.

Rounding Numbers

The calculator stores and calculates using 12-digit numbers. When 12 digit accuracy is not

desirable, use \}to round the number to the displayed format before using it in a

calculation. Rounding numbers is useful when you want the actual (dollars and cents) monthly payment.
