Class:

Elemental function

Syntax:

RESULT = IAND(I, J)

Arguments:
IThe type shall be INTEGER or a boz-literal-constant.
JThe 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)
