[TD_SYSFNLIB.] ROTATERIGHT ( target_arg, num_bits_arg )
- Name of the database where the function is located.
- A numeric or variable byte expression.
- An integer expression indicating the number of bit positions to rotate.
|IF...||THEN the function...|
|num_bits_arg is equal to zero||returns target_arg unchanged.|
|num_bits_arg is negative||rotates the bits to the left instead of the right.|
|target_arg and/or num_bits_arg are NULL||returns NULL.|
|num_bits_arg is larger than the size of target_arg||rotates (num_bits_arg MOD sizeof(target_arg )) bits.
The scope of the rotation operation is bounded by the size of the target_arg expression.
When operating against an integer value (BYTEINT, SMALLINT, INTEGER, or BIGINT), rotating a bit into the most significant position will result in the integer becoming negative. This is because all integers in Vantage are signed integers.
