Description: | Performs a circular shift of the rightmost bits. | ||

Class: | Elemental function; Generic | ||

Arguments: |
I | Must be of type integer. | |

SHIFT | Must be of type integer. The absolute value for SHIFT must be less than or equal to SIZE. | ||

SIZE (opt) | Must be of type integer. The value of SIZE must be positive and must not exceed BIT_SIZE (I). If SIZE is omitted, it is assumed to have the value of BIT_SIZE (I). | ||

Results: |
The result type is the same as I. The
result value is obtained by circular shifting the SIZE rightmost
bits of I by SHIFT positions. If SHIFT is positive, the shift is to
the left; if SHIFT is negative, the shift is to the right. If SHIFT
is zero, no shift is performed.
No bits are lost. Bits in I beyond the value specified by SIZE are unaffected. For more information on bit functions, see Section 9.2.3. The model for the interpretation of an integer value as a sequence of bits is shown in Section D.3. |
