This commit adds the math.factorial function in two variants: - squared difference, which is faster than the naive version, relatively compact, and non-recursive; - a mildly optimised recursive version, faster than the above one. There are some more optimisations that could be done, but they tend to take more code, and more storage space. The recursive version seems like a sensible compromise. The new function is disabled by default, and uses the non-optimised version by default if it is enabled. The options are MICROPY_PY_MATH_FACTORIAL and MICROPY_OPT_MATH_FACTORIAL. |

README
This directory contains tests for various functionality areas of MicroPython. To run all stable tests, run "run-tests" script in this directory. Tests of capabilities not supported on all platforms should be written to check for the capability being present. If it is not, the test should merely output 'SKIP' followed by the line terminator, and call sys.exit() to raise SystemExit, instead of attempting to test the missing capability. The testing framework (run-tests in this directory, test_main.c in qemu_arm) recognizes this as a skipped test. There are a few features for which this mechanism cannot be used to condition a test. The run-tests script uses small scripts in the feature_check directory to check whether each such feature is present, and skips the relevant tests if not. 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.
