XOR
The XOR function is used to perform a binary logical exclusion on two
numbers.
Syntax
result = number1 XOR number2
The XOR operator also performs a bit-wise comparison of identically
positioned bits in two numbers (may be variables or the results of expressions)
and sets the corresponding bit in result according to the following truth table:
If bit in
number1 is And bit in
number2 is The result is
0 0 0
0 1 1
1 0 1
1 1 0
Derived Math Functions
The following is a list of nonintrinsic mathematical functions that can be derived
from the intrinsic math functions provided with CRBasic:
