Random Numbers And Exchange Key; Unit Conversion; Statistics Calculation; Computing Single Variable Statistics - Citizen SR-260N Instruction Manual

Complex numbers are generally represented as a + b i, where a is a
real and b is imaginary.
[ 2ndF ] [ CPLX ] 7
[ a ] 9 [ +/– ] [ b ] [ + ]
( 7– 9 i ) + (15 +
15 [ a ] 10 [ b ] [ = ]
10 i) = ?
[ b ]
(Note) : Memory calculation is available in complex number mode.

Random numbers and Exchange key

Random key
Pressing [ RND ] key enables the display to generate random
numbers between 0.000 and 0.999.
Press [ 2ndF ] [ RND ]
Exchange key
Pressing [ 2ndF ] [ X ↔ Y ] enables the displayed value to exchange as
the previous value.
123 [ + ] 456 [ = ]
[ 2ndF ] [ X ↔ Y ]
123 + 456 = ?
[ 2ndF ] [ X ↔ Y ]

Unit conversion

in ↔ cm
12 [ A B ] [ 2ndF ]
12 in = ? cm
[ in ↔ cm ]
98 [ 2ndF ] [ A B ]
98 cm = ? in
[ 2ndF ] [ in ↔ cm ]
(Note) : The operating procedure for unit conversion key, [ ° F ↔ ° C ],
[ mmHg ↔ kpa ], [ gal ↔ I ], [ lb ↔ kg ], [ oz ↔ g ], is similar to the
above example.

Statistics calculation

Computing single variable statistics

Select the mode by pressing [ STAT ] key and make sure
"STAT" indictor appears on the display.
The STAT mode enables you to calculate the following single variable
statistics :
n number of all data
Σ x sum of all data
