Base-n mode calculation

Converting between bases

The unit enables you to calculate in number base other than decimal. The calculator can add, subtract, multiply, and divide binary, octal, and hexadecimal numbers. Select the number base you want by the [ÆBIN], [ÆOCT], [ÆHEX], [ÆDEC] keys. The BIN, OCT, and HEX indicators show you which base you are using. (if none of the indicators appears in the appear in the display, you are in decimal base.)

The keys active in each base is described as follows :

Binary base : [ 0 ]	[ 1 ]
Octal base : [ 0 ] ~ [ 7 ]
Decimal base : [ 0 ] ~ [ 9 ]
Hexadecimal base : [ 0 ] ~ [ 9 ], [ A ] ~ [ F ]
	[ 2ndF ] [ÆDEC ] 31	DEG			3	1.
31 (base 10)
	[ 2ndF ] [ÆBIN ]	DEG		BIN
= ? (base 2)
			1 1 1 1			1.
= ?(base 8)	[ 2ndF ] [ÆOCT ]	DEG		OCT	3	7.
= ? (base 16)
	[ 2ndF ] [ÆHEX ]	DEG		HEX	1	F.
	[ 2ndF ] [ÆHEX ] 4	DEG		HEX	6	C.
4 X 1B (base 16)	[ x ] 1B [ = ]
	[ 2ndF ] [ÆBIN ]	DEG		BIN
= ? (base 2)
			1 1 0 1 1 0			0.
= ? (base 10)
	[ 2ndF ] [ÆDEC ]	DEG	1 0 8. 0			0
= ? (base 8)
	[ 2ndF ] [ÆOCT ]	DEG		OCT
			1		5	4.

Negative and Complements

In binary, octal, and hexadecimal bases, the calculator represents negative numbers using complement notation. The complement’s is the result of subtracting that number from 10000000000 in that number’s base by pressing [ +/– ] key in non-decimal bases.

Calculate the complement of binary number 11011

[ 2ndF ] [ÆBIN ] 11011 [ +/– ]

DEG BIN

1 1 1 1 1 0 0 1 01.

Complex numbers calculation

Select the complex numbers mode by pressing [ CPLX ] key and make sure “ CPLX “ indicator appears on the display. The calculator enables you to add, subtract, multiply, and divide complex numbers.
