DSHIFTR (The GNU Fortran Compiler) (original) (raw)


8.91 DSHIFTR — Combined right shift

Synopsis:

RESULT = DSHIFTR(I, J, SHIFT)

Description:

DSHIFTR(I, J, SHIFT) combines bits of I and J. The leftmost SHIFT bits of the result are the rightmost SHIFTbits of I, and the remaining bits are the leftmost bits ofJ.

Class:

Elemental function

Arguments:

I Shall be of type INTEGER, UNSIGNED or a BOZ constant.
J Shall be of type INTEGER, UNSIGNED or a BOZ constant. If both I and J have INTEGER or UNSIGNED type, then they shall have the same type and kind type parameter. Iand 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 SHIFTshall be less than or equal to BIT_SIZE(I); otherwise,SHIFT shall be less than or equal to BIT_SIZE(J).

Return value:

The return value is the same type and type kind parameter as I or, if I is a BOZ constant, J.

Standard:

Fortran 2008 and later, extension for UNSIGNED (see Unsigned integers)
