k Logical Operators (AND, OR, NOT, XOR) [OPTN] - [LOGIC]
The logical operator menu provides a selection of logical operators.
• { And } / { Or } / { Not } / { Xor } ... {logical AND}/{logical OR}/{logical NOT}/{logical XOR}
• Be sure to specify Comp for Mode in the Setup screen.
Example What is the logical AND of A and B when A = 3 and B = 2?
A AND B = 1

u About Logical Operations
• A logical operation always produces either 0 or 1 as its result.
• The following table shows all of possible results that can be produced by AND, OR and XOR
operations.
Value or Expression A Value or Expression B A AND B A OR B A XOR B
A ≠ 0 B ≠ 0
1 1 0
A ≠ 0
B = 0 0 1 1
A = 0
B ≠ 0
0 1 1
A = 0 B = 0 0 0 0
• The following table shows the results produced by the NOT operation.
Value or Expression A NOT A
A ≠ 0
0
A = 0 1
5. Numerical Calculations
The following explains the numerical calculation operations included in the function menu
displayed when K4(CALC) ( 3(CALC) on the fx-7400GIII) is pressed. The following
calculations can be performed.
• { Int÷ } / { Rmdr } / { Simp } ... {quotient}/{remainder}/{simplification}
• { Solve } / {
d / dx } / { d

} / { ∫ dx } / { SolvN } ... {equality solution}/{differential}/{quadratic differential}/
{integration}/{ f ( x ) function solution}
• { FMin } / { FMax } / { Σ ( } / { log

b } ... {minimum value}/{maximum value}/{summation}/{logarithm
