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

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

(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

Pressing @ or 2 will cause the exponent display for the

number being displayed to change in multiples of 3, with the mantissa adjusted

accordingly.
