Logical and Negation Operations
Logical and negation operations are performed by pressing
and
selecting [Logic Operation], and then selecting the desired command
(Neg, Not, and, or, xor, xnor) from the menu that appears. All of the
examples below are performed in the binary mode.
Example 5: To determine the logical AND of 1010
2
and 1100
2
(1010
2
and
1100
2
)
1010
– [Logic Operation] > [and]
1100
Example 6: To determine the bitwise complement of 1010
2
(Not(1010
2
))
– [Logic Operation] > [Not]
1010
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 values, the calculator merely adds a minus sign.
Matrix Calculations
Use the Matrix app to perform calculations involving matrices of up to 4
rows by 4 columns.
General Procedure for Performing a Matrix
Calculation
To perform a matrix calculation, use the special matrix variables (MatA,
MatB, MatC, MatD) as shown in the example below.
Example 1: To calculate
• For multiplication (Matrix 1 × Matrix 2), the number of columns in Matrix
1 must match the number of rows in Matrix 2. Otherwise, an error
occurs.
1. Press
, select the Matrix app icon, and then press .
