NOT Function

Description

The NOT function returns the bit-wise logical complement of an INTEGER argument.

Syntax
 
NOT (i)
 

Arguments

i is an INTENT(IN) scalar or array of type INTEGER.

Result

The result is an INTEGER of the same kind as i. Its value is the value of i with each of its bits complemented (zeros changed to ones and ones changed to zeros).

Example
       integer :: ia(3)=(/-1,0,1/)
       write(*,*) not(-1) ! writes 0
       write(*,*) not(0)  ! writes -1
       write(*,*) not(ia) ! writes 0 -1 -2
