Previously, mpz was restricted to using at most 15 bits in each digit, where a digit was a uint16_t. With this patch, mpz can use all 16 bits in the uint16_t (improvement to mpn_div was required). This gives small inprovements in speed and RAM usage. It also yields savings in ROM code size because all of the digit masking operations become no-ops. Also, mpz can now use a uint32_t as the digit type, and hence use 32 bits per digit. This will give decent improvements in mpz speed on 64-bit machines. Test for big integer division added.
This directory contains tests for various functionality areas of MicroPython. To run all stable tests, run "run-tests" script in this directory. Note that bytecode tests are not yet stable and should be run separately in "bytecode" subdirectory. When creating new tests, anything that relies on float support should go in the float/ subdirectory. Anything that relies on import x, where x is not a built-in module, should go in the import/ subdirectory.
