Notation modes only affect the way an answer is displayed
on the home screen. Numeric answers can be displayed
with up to 10 digits and a two-digit exponent. You can
enter a number in any format.
Normal notation mode is the usual way we express
numbers, with digits to the left and right of the decimal, as
in
12345.67.
Sci (scientific) notation mode expresses numbers in two
parts. The significant digits display with one digit to the left
of the decimal. The appropriate power of 10 displays to the
right of
E
, as in 1.234567
E
4.
Eng (engineering) notation mode is similar to scientific
notation. However, the number can have one, two, or three
digits before the decimal; and the power-of-10 exponent is
a multiple of three, as in
12.34567
E
3.
Note
: If you select
Normal
notation, but the answer cannot display in
10 digits (or the absolute value is less than .001), the TI

83 expresses
the answer in scientific notation.

the sign and decimal.
0123456789 (fixed) decimal mode specifies the number of
digits (
0 through 9) to display to the right of the decimal.
