The number system (10, 16, 2 , 8 ) is set by pressing [ 2nd ] [ dhbo ]
to display the menu, making one of the items underlined followed
[ ENTER ]. A corresponding symbol – "
d
", "
h
", "
b
", "
o
" appears
on the display. (The default setting is
d
: decimal base). See
Example 39.
(Note) : The total range of numbers handled in this mode is 0, 1,
2, 3, 4, 5, 6, 7, 8, 9, A, B, C, D, E, F. If values not valid for
the particular number system are used, attach the
corresponding designator (
d
,
h
,
b
,
o
), or an error
message will appear.
Binary base (
b
) : 0, 1
Octal base (
o
) : 0, 1, 2, 3, 4, 5, 6, 7
Decimal base (
d
) : 0, 1, 2, 3, 4, 5, 6, 7, 8, 9
Hexadecimal base (
h
) : 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, A, B, C, D, E, F
Pressing [
] can use block function to display a result in octal or
binary base which exceeds 8 digits. The system is designed to
display up to 4 blocks. See Example 40.

Negative expression
z
In binary, octal, and hexadecimal bases, the calculator represents
negative numbers using complement notation. The complement is
the result of subtracting that number from 10000000000 in that
number's base by pressing [ NEG ] key in non-decimal bases.
See Example 41.

Basic arithmetic operations for bases
z
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. See Example 42.

Logical operation
Logical operations are performed through logical products (AND),
negative logical (NAND), logical sums (OR), exclusive logical sums
