Example 4:
To determine the logical XNOR of 1111
2
and 101
2
(1111
2
xnor
101
2
)
1111
(BASE)
(xnor) 101
1111111111110101
Example 5:
To determine the bitwise complement of 1010
2
(Not(1010
2
))
(BASE)
(Not) 1010
1111111111110101
Example 6:
To negate (take the two's complement) of
101101
2
(Neg(101101
2
))
(BASE)
(Neg) 101101
1111111111010011
Note
• In the case of a negative binary, octal or hexadecimal value, the calculator converts
the value to binary, takes the two's complement, and then converts back to the original
number base. For decimal (base-10) values, the calculator merely adds a minus sign.
Equation Calculations (EQN)
