XOR
Result = Expression XOR Expression
Compute the logical
exclusive or of two boolean expressions, or the numerical
exclusive or of two integer numbers.
Strings and objects are automatically converted to booleans.
A null string or a null object is converted to
FALSE, other values are converted to
TRUE.
Поскольку 3.17
If one of the operands is a floating value, an error is raised.
Before Gambas 3.17, the floating point values were silently converted to Boolean, leading to a useless result.
The logical XOR operator connects two boolean expressions and returns a true or false value. The result returned by this operation is shown in the following table:
|
A
|
B
|
A XOR B
|

The numerical XOR operator connects two integer values and returns an integer value. Each corresponding bit of the specified values is combined according to the following table:

Examples
PRINT TRUE XOR FALSE
PRINT TRUE XOR TRUE
PRINT 7, Bin(7, 16)
PRINT 11, Bin(11, 16)
PRINT 7 XOR 11, Bin(7 XOR 11, 16)
7 0000000000000111
11 0000000000001011
12 0000000000001100
