NOT

インテル® Fortran コンパイラー 14.0 ユーザー・リファレンス・ガイド

Elemental Intrinsic Function (Generic): Returns the logical complement of the argument.

result = NOT (i)

i	(Input) Must be of type integer.

結果

The result type and kind is the same as i. The result value is obtained by complementing i bit-by-bit according to the following truth table:

  I   NOT (I)

  1      0

  0      1

The model for the interpretation of an integer value as a sequence of bits is shown in Model for Bit Data.

If I has a value equal to 10101010 (base 2), NOT (I) has the value 01010101 (base 2).

The following shows another example:

 INTEGER(2) i(2), j(2)

 i = (/4, 132/)          ! i(1) = 0000000000000100

                         ! i(2) = 0000000010000100

 j = NOT(i)              ! returns (-5,-133)

                         ! j(1) = 1111111111111011

                         ! j(2) = 1111111101111011
