NAME

NOT, INOT, JNOT, KNOT - Perform a logical complement

SYNOPSIS

NOT ([I=]i)
INOT ([I=]i)
JNOT ([I=]i)
KNOT ([I=]i)

STANDARDS

Fortran

Fortran extensions: INOT, JNOT, KNOT

DESCRIPTION

The NOT, INOT, JNOT, and KNOT intrinsic functions perform a logical complement. They accept the following argument:

i: Must be of type integer. For INOT, must be of type integer (KIND=2). For JNOT, must be of type integer (KIND=4). For KNOT, must be of type integer (KIND=8).

These are elemental intrinsic functions. The names of these intrinsics cannot be passed as arguments.

RETURN VALUES

The result type and type parameter are the same as i.

The result has the value obtained by complementing i bit-by-bit according to the following truth table:

--------------------
i       NOT(i)
--------------------
1       0
0       1
--------------------

The bit model defines the interpretation of an integer value as a sequence of bits. For more information on the bit model, see the models(3i) man page.

EXAMPLES

If I is represented by the string of bits 01010101, NOT(I) has the binary value 10101010.
