simplified Boolean expression if either of the original

xor
Compares two real integers bit-by-bit using an
operation. Internally, both integers are converted to
signed, 32-bit binary numbers. When corresponding
bits are compared, the result is 1 if either bit (but not
both) is 1; the result is 0 if both bits are 0 or both
bits are 1. The returned value represents the bit
results, and is displayed according to the
mode.
You can enter the integers in any number base. For
a binary or hexadecimal entry, you must use the 0b
or 0h prefix, respectively. Without a prefix, integers
are treated as decimal (base 10).
If you enter a decimal integer that is too large for a
signed, 32-bit binary form, a symmetric modulo
operation is used to bring the value into the
appropriate range.
