IAND — Bitwise logical and#

IAND(I, J)#

Bitwise logical AND.

Parameters:
  • 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.

Returns:

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 — Convert to integer type occurred.

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)
Example:
PROGRAM test_iand
  INTEGER :: a, b
  DATA a / Z'F' /, b / Z'3' /
  WRITE (*,*) IAND(a, b)
END PROGRAM
