Order Of Operations - Citizen SR-260 Instruction Manual

On the contrary, if fewer than the selected number of decimal places
is keyed, it will be padded with trailing zero.
(Ex.) : Fix the display at 4 decimal places, then key in 4.23
Step 1 : press [ 2ndF ] [ TAB ] 4
Step 2 : key in 4.23 [ = ]
Scientific display format
In Scientific display format, the number 891500 can be shown in scientific
format as 8.915 x 10
exponent of 10.
(Ex.) : 7132 x 125 is displayed in scientific display format.
Step 1 : key in 7132 [ x ] 125 [ = ]
Step 2 : press [ F↔E ]
(in floating point format)
Besides, entry can be made in scientific notation by using the [ E X P ]
key after entering the mantissa.
(Ex.) : Key the number 4.82296 x 10
Step : key in 4.82296 [ EXP ] 5
(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
(Ex.) : Convert 15V into 15000mV (V : Volt)
Step 1 : key in 15
Step 2 : press [ ENG ] twice
(Ex.) : Convert 15V into 0. 015KV (V : Volt)
Step 1 : key in 15
Step 2 : press [ 2ndF ] [

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
, X!, %, RND, ENG,
4) Fractions
