py/formatfloat: Fix further cases of buffer overflow in formatting. Includes extensive test cases to catch hopefully all cases where buffer might overflow.
2016-03-29 22:07:15 +01:00
# test formatting floats with large precision, that it doesn't overflow the buffer
tests: Format all Python code with black, except tests in basics subdir. This adds the Python files in the tests/ directory to be formatted with ./tools/codeformat.py. The basics/ subdirectory is excluded for now so we aren't changing too much at once. In a few places `# fmt: off`/`# fmt: on` was used where the code had special formatting for readability or where the test was actually testing the specific formatting.
