If the absolute value of <var>SHIFT</var> is greater than <code>BIT_SIZE(I)</code>, the value is undefined. Bits shifted out from the right end are lost. The fill is arithmetic: the bits shifted in from the left end are equal to the leftmost bit, which in two's complement representation is the sign bit. <p>This function has been superseded by the <code>SHIFTA</code> intrinsic, which is standard in Fortran 2008 and later. <br><dt><em>Standard</em>:<dd>GNU extension <br><dt><em>Class</em>:<dd>Elemental function <br><dt><em>Syntax</em>:<dd><code>RESULT = RSHIFT(I, SHIFT)</code> <br><dt><em>Arguments</em>:<dd> <p><table summary=""><tr align="left"><td valign="top" width="15%"><var>I</var> </td><td valign="top" width="70%">The type shall be <code>INTEGER</code>. <br></td></tr><tr align="left"><td valign="top" width="15%"><var>SHIFT</var> </td><td valign="top" width="70%">The type shall be <code>INTEGER</code>. <br></td></tr></table> <br><dt><em>Return value</em>:<dd>The return value is of type <code>INTEGER</code> and of the same kind as <var>I</var>. <br><dt><em>See also</em>:<dd><a href="ISHFT.html#ISHFT">ISHFT</a>, <a href="ISHFTC.html#ISHFTC">ISHFTC</a>, <a href="LSHIFT.html#LSHIFT">LSHIFT</a>, <a href="SHIFTA.html#SHIFTA">SHIFTA</a>, <a href="SHIFTR.html#SHIFTR">SHIFTR</a>, <a href="SHIFTL.html#SHIFTL">SHIFTL</a> </dl> </body></html>
