Bitwise logical AND
.
This intrinsic routine is provided for backwards compatibility with GNU Fortran 77. For integer arguments, programmers should consider the use of the IAND intrinsic defined by the Fortran standard.
GNU extension
Function
RESULT = AND(I, J)
I | The type shall be either a scalar INTEGER type or a scalar LOGICAL type or a boz-literal-constant. |
J | The type shall be the same as the type of I or a boz-literal-constant. I and J shall not both be boz-literal-constants. If either I or J is a boz-literal-constant, then the other argument must be a scalar INTEGER . |
The return type is either a scalar INTEGER
or a scalar LOGICAL
. If the kind type parameters differ, then the smaller kind type is implicitly converted to larger kind, and the return has the larger kind. 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.
