## 9.3.76 ISHFTC (I, SHIFT [, SIZE])

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.

Specific Name | Argument Type | Result Type
