BITXNOR Function (DataBasic) (M618703+BITXNOR_F.HTM)
Returns the bitwise logical XNOR of two expressions.
BITXNOR(expression1,expression2)
expressionA valid DataBasic expression or any string, substring or value; may be expressed as a variable name, a value, or a string enclosed in quote marks that evaluates to a decimal number (of which only the integer part is used).
Each expression is converted to a hexadecimal number before the logical XNOR is performed. If one expression is shorter than the other the shorter one is first sign extended to be the same length. There is no limit to the length that can be accommodated.
| Expression | Bit string |
|---|---|
| Expression A | 0011

| Expression B | 0101 |
| Function | Result |
| BITXNOR(A,B) | 1001
