expression
Returns true or false or a simplified form of the
original entry.
Returns true if either or both expressions simplify
to true. Returns false only if both expressions
evaluate to false.

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 is 1; the result is 0 only if both bits are
0. 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.
