RSHIFT (The GNU Fortran Compiler)

### 8.241 `RSHIFT` — Right shift bits ¶

Synopsis:

  `RESULT = RSHIFT(I, SHIFT)`

Description:

  `RSHIFT` returns a value corresponding to I with all of the bits shifted right by SHIFT places. SHIFT shall be nonnegative and less than or equal to `BIT_SIZE(I)`, otherwise the result 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.

  This function has been superseded by the `SHIFTA` intrinsic, which is standard in Fortran 2008 and later.

Class:

  Elemental function

Arguments:

  I | The type shall be `INTEGER`.
  SHIFT | The type shall be `INTEGER`.

Return value:

  The return value is of type `INTEGER` and of the same kind as I.

Standard:

  GNU extension
