Citizen Systems SR-260N Statistics calculation, Random numbers and Exchange key, Unit conversion

Complex numbers are generally represented as a + b i, where a is a real and b is imaginary.

	[ 2ndF ] [ CPLX ] 7	DEG		CPLX
( 7– 9 i ) + (15 +	[ a ] 9 [ +/– ] [ b ] [ + ]		2 2.		0 0
	15 [ a ] 10 [ b ] [ = ]
10 i) = ?
	[ b ]	DEG		CPLX
			1.		0 0

(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

DEG

0. 2 3 1

Pressing [ 2ndF ] [ X↔Y ] enables the displayed value to exchange as the previous value.

123 + 456 = ?

123 [ + ] 456 [ = ]

[ 2ndF ] [ X↔Y ]

[ 2ndF ] [ X↔Y ]

DEG

Unit conversion

↔
in cm
12 in = ? cm	12 [ AÆB ] [ 2ndF ]		DEG
	[ in↔cm ]	3		0. 4 8
98 cm = ? in	98 [ 2ndF ] [ AÅB ]		DEG
	[ 2ndF ] [ in↔cm ]	3		8. 5 8

(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 :

nnumber of all data Σx sum of all data
