Logical and Negation Operations
Your calculator provides you with logical operators (and, or, xor, xnor) and
functions (Not, Neg) for logical and negation operations on binary values.
Use the menu that appears when you press 13(BASE) to input these
logical operators and functions.
All of the following examples are performed in the binary mode (l(BIN)).
To determine the logical AND of 1010
2
and 1100
2
(1010
2
and 1100
2
)
A 1010 13(BASE)1(and) 1100 =
0000000000001000
To determine the logical OR of 1011
2
and 11010
2
(1011
2
or 11010
2
)
A 1011 13(BASE)2(or) 11010 =
0000000000011011
To determine the logical XOR of 1010
2
and 1100
2
(1010
2
xor 1100
2
)
A 1010 13(BASE)3(xor) 1100 =
0000000000000110
To determine the logical XNOR of 1111
2
and 101
2
(1111
2
xnor 101
2
)
A 1111 13(BASE)4(xnor) 101 =
1111111111110101
To determine the bitwise complement of 1010
2
(Not(1010
2
))
A13(BASE)5(Not) 1010 )=
1111111111110101
To negate (take the two’s complement) of 101101
2
(Neg(101101
2
))
A13(BASE)6(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)
You can use the following procedure in the EQN Mode to solve simultaneous
linear equations with two or three unknowns, quadratic equations, and cubic
equations.
1. Press N5(EQN) to enter the EQN Mode.
2. On the menu that appears, select an equation type.
To select this calculation type: Press this key:
Simultaneous linear equations with two
unknowns
1(a
n
X + b
n
Y = c
n
)
Simultaneous linear equations with
three unknowns
2(a
n
X + b
n
Y + c
n
Z = d
n
)
