Returns true or false or a simplified form of

integer
Compares two real integers bit-by-bit using
an
or
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
Base
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.
Note: See
xor
.

In Bin base mode:
0b100101 or 0b100
¸
0b100101
Note: A binary entry can have up to 32
digits (not counting the 0b prefix). A
hexadecimal entry can have up to 8 digits.
Important:
Zero, not the letter O.
