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.
