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
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
