1-22 Getting Started
Scientific Format ()
SCI format displays a number in scientific notation (one digit before the "" or ""
radix mark) with up to 11 decimal places and up to three digits in the exponent.
After the prompt, _, type in the number of decimal places to be displayed. For
10 or 11 places, press
or . (The mantissa part of the number will
always be less than 10.)
For example, in the number
, the "2", "3", "4", and "6" are the
decimal digits you see when the calculator is set to SCI 4 display mode. The "5"
following the "E" is the exponent of 10: 1.2346 × 10
5
.
If you enter or calculate a number that has more than 12 digits, the additional
precision is not maintained.
Engineering Format ()
ENG format displays a number in a manner similar to scientific notation, except that
the exponent is a multiple of three (there can be up to three digits before the "" or
"" radix mark). This format is most useful for scientific and engineering calculations
that use units specified in multiples of 10
3
(such as micro–, milli–, and kilo–units.)
After the prompt, _, type in the number of digits you want after the first
significant digit. For 10 or 11 places, press or .
For example, in the number
, the "2", "3", "4", and "6" are the
significant digits after the first significant digit you see when the calculator is
set to ENG 4 display mode. The "3" following the "
" is the (multiple of 3)
exponent of 10: 123.46 x 10
3
.,
Pressing @ or 2 will cause the exponent display for the
number being displayed to change in multiples of 3, with the mantissa adjusted
accordingly.
