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 Teradata Database are signed integers.
