8.137 IAND — Bitwise logical and

Description:
Bitwise logical AND.
Standard:
Fortran 90 and later, with boz-literal-constant Fortran 2008 and later, has overloads that are GNU extensions
Class:
Elemental function
Syntax:
RESULT = IAND(I, J)
Arguments:

I The type shall be INTEGER or a boz-literal-constant.
J The type shall be INTEGER with the same kind type parameter as I or a boz-literal-constant. I and J shall not both be boz-literal-constants.

Return value:
The return type is INTEGER with the kind type parameter of the arguments. A boz-literal-constant is converted to an INTEGER with the kind type parameter of the other argument as-if a call to INT occurred.
Example:
          PROGRAM test_iand
            INTEGER :: a, b
            DATA a / Z'F' /, b / Z'3' /
            WRITE (*,*) IAND(a, b)
          END PROGRAM
     

Specific names:

BIAND(A) INTEGER(1) A INTEGER(1) GNU extension
IIAND(A) INTEGER(2) A INTEGER(2) GNU extension
