DSHIFTR(I, J, SHIFT)
combines bits of I and J. The leftmost SHIFT bits of the result are the rightmost SHIFT bits of I, and the remaining bits are the leftmost bits of J.
Fortran 2008 and later
Elemental function
RESULT = DSHIFTR(I, J, SHIFT)
I | Shall be of type INTEGER or a BOZ constant. |
J | Shall be of type INTEGER or a BOZ constant. If both I and J have integer type, then they shall have the same kind type parameter. I and J shall not both be BOZ constants. |
SHIFT | Shall be of type INTEGER . It shall be nonnegative. If I is not a BOZ constant, then SHIFT shall be less than or equal to BIT_SIZE(I) ; otherwise, SHIFT shall be less than or equal to BIT_SIZE(J) . |
If either I or J is a BOZ constant, it is first converted as if by the intrinsic function INT
to an integer type with the kind type parameter of the other.
