And the version with default units: https://github.com/KiCad/kicad-python/pull/7/files
Looks quite clean to me, and yet all the precision from native units is retained, plus we can do things like: >> p = Point((2**31-1) * nm, (-(2**31)+1) *nm) >> p.nm (2147483647.0, -2146483648.0) >>> p=Point(1,2) >>> p.inch (0.03937007874015748, 0.07874015748031496) >>> p=Point(1*inch, 1*inch) >>> p.inch (1.0, 1.0) >>> p.mm (25.4, 25.4) >>> p.nm (25400000.0, 25400000.0) >>> p.rotate(90, around=(0,0)) >>> p Point(-25.4, 25.4) Miguel Ángel Ajo On Sunday, 25 de January de 2015 at 03:03, Miguel Ángel Ajo wrote: > A little experiment, with the suggested * mm / * inch notation. > > https://github.com/KiCad/kicad-python/pull/6/files [1] > > Look specially at the tests (last files). > > Feel free to comment over the code. > > If we could default to mm (my preferred) or inches, we could > save a lot of code (specially to process by human brains > reading python) while retaining all the precision. > > > Best, > Miguel Ángel Ajo > [1] Note: 2 builds failed because I didn’t make the C++ “pcbnew” module for > the tests. > > > On Sunday, 25 de January de 2015 at 02:56, Tomasz Wlostowski wrote: > > > On 25.01.2015 02:50, Miguel Ángel Ajo wrote: > > > > > > I was just testing that. > > > > > > Python floats (in all architectures) are double, so the 52 bit fraction > > > (11 bit exp) is always > > > going to hold more information that the 32bits wxPoint /wxSize can hold. > > > > > > > > > Hi Miguel, > > > > Sorry, I'm a C/C++ guy, so float defaults for me to 32 bits ;) Doubles > > look ok, although the decimal part will be anyway truncated on the way > > from Python to C++ (if we decide to keep the nm as default unit) > > > > Cheers, > > T. > > > > > > > > > _______________________________________________ > Mailing list: https://launchpad.net/~kicad-developers > Post to : [email protected] > (mailto:[email protected]) > Unsubscribe : https://launchpad.net/~kicad-developers > More help : https://help.launchpad.net/ListHelp > > >
