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 [
→
BIN], [
→
OCT], [
→
HEX], [
→
DEC] 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 ]
