### 8.257 `SHIFTL` — Left shift ¶

Synopsis:

  `RESULT = SHIFTL(I, SHIFT)`

Description:

  `SHIFTL` returns a value corresponding to I with all of the bits shifted left 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 left end are lost, and bits shifted in from the right end are set to 0.

Class:

  Elemental function

Arguments:

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

Return value:

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