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.

Step 1: key in 7132 [ x ] 125 [ = ]		DEG
	8		9	1	5	0	0.
Step 2: press [ F↔E ]		DEG					05
				8. 9		1	5

(in floating point format)

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

(Ex.) : Key the number 4.82296 x 10 5

Step :key in 4.82296 [ EXP ] 5		DEG				05
	4. 8		2	2	9	6

(in floating point format)

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

Step 1: key in 15

Step 2: press [ ENG ] twice

(Ex.) : Convert 15V into 0. 015KV

Step 1: key in 15

Step 2: press [ 2ndF ] [ Å ] twice

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, x2, 1/x,

√, π, 3√, x!, %, RND, ENG,	,	, and 6 units
conversion.
