DSHIFTL — Combined left shift
DSHIFTL(I, J, SHIFT)combines bits of I and J. The rightmost SHIFT bits of the result are the leftmost SHIFT bits of J, and the remaining bits are the rightmost bits of I.
Fortran 2008 and later
RESULT = DSHIFTL(I, J, SHIFT)
I Shall be of type
INTEGERor a BOZ constant.
J Shall be of type
INTEGERor 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
- Return value:
If either I or J is a BOZ constant, it is first converted as if by the intrinsic function
INTto an integer type with the kind type parameter of the other.
