Scientific display format
In Scientific display format, the number 891500 can be shown in
scientific format as 8.915 x 10
05 , where 8.915 is called the mantissa
and 5 is as the exponent of 10.
(Ex.) : 7132 x 125 is displayed in scientific display format.

Besides, entry can be made in scientific notation by using the
[EXP] key after entering the mantissa.

Engineering display format
The format is similar to the scientific format, expect the mantissa can
have up to three digits left of the decimal, instead of only one, and the
exponent is always a multiple of three. It is useful for engineers to
convert units based on multiples of 10
3 .
(Ex.) : Convert 15V into 15000mV (V : Volt)

Order of operations
Each calculation is performed in the following order of precedence :
1) Operation in parenthesis.
2) Functions required pressing the function key before entering,
for example, [ DATA ] in STAT mode and [ EXP ] key.
3) Functions required inputing values before pressing the function
key, for example, cos, sin, tan, cos −1 , sin −1 , tan −1 , log, ln, x 2 , 1/x,
√ , π, 3 √ , x!, %, RND, ENG, , , and 6 units
conversion.
