py/objfloat: Fix abs(-0.0) so it returns 0.0. Nan and inf (signed and unsigned) are also handled correctly by using signbit (they were also handled correctly with "val<0", but that didn't handle -0.0 correctly). A test case is added for this behaviour. 2018-09-27 05:21:25 +00:00			`# test builtin abs function with float args`

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. 2020-03-23 02:26:08 +00:00			`"1.0",`
