RShift Intrinsic
................

     RShift(I, SHIFT)

RShift: `INTEGER' function, the `KIND=' value of the type being that of
argument I.

I: `INTEGER'; scalar; INTENT(IN).

SHIFT: `INTEGER'; scalar; INTENT(IN).

Intrinsic groups: `f2c'.

Description:

   Returns I shifted to the right SHIFT bits.

   Although similar to the expression `I/(2**SHIFT)', there are
important differences.  For example, the sign of the result is
undefined.

   Currently this intrinsic is defined assuming the underlying
representation of I is as a two's-complement integer.  It is unclear at
this point whether that definition will apply when a different
representation is involved.

   Note: RShift Intrinsic, for the inverse of this function.

   Note: IShft Intrinsic, for information on a more widely available
right-shifting intrinsic that is also more precisely defined.
