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
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.
