not integer1
⇒ ⇒ ⇒ ⇒
integer
Returns the one’s complement of a real integer.
Internally,
integer1
is converted to a signed, 32-bit
binary number. The value of each bit is flipped (0
becomes 1, and vice versa) for the one’s
complement. Results are displayed according to
the
Base
mode.
You can enter the integer in any number base. For
a binary or hexadecimal entry, you must use the
0b or 0h prefix, respectively. Without a prefix, the
integer is 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: A binary entry can have up to 32 digits (not
counting the 0b prefix). A hexadecimal entry can have
up to 8 digits.
