If divides , set and return GR_SUCCESS; if not, set to zero and return GR_DOMAIN; if divisibility cannot be decided, return GR_UNABLE. Division by zero gives GR_DOMAIN (except in the zero ring).
The heap version is the heap division algorithm of Monagan and Pearce, which stops as soon as a remainder term appears that the leading monomial of does not divide. The heap_threaded version splits the work among threads for large inputs over thread-safe rings and otherwise calls the serial algorithm. The default handles a single-term divisor directly, requires an integral domain for the general case (GR_UNABLE otherwise, since this is also the method behind gr_div), and uses the threaded version when , , the ring is thread-safe and threads are available.
