9.90 DSHIFTL — Combined left shift
- Description:
-
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. - Standard:
-
Fortran 2008 and later
- Class:
-
Elemental function
- Syntax:
-
RESULT = DSHIFTL(I, J, SHIFT)
- Arguments:
-
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 toBIT_SIZE(I)
; otherwise, SHIFT shall be less than or equal toBIT_SIZE(J)
. - Return value:
-
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. - See also:
