TI-83 Plus Operating the TI-83 Plus Silver Edition 21
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
1.234567E4
.
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
12.34567E3
.
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 Plus expresses the answer in
scientific notation.
