The plan goes like this:
- eeschema still uses int in decidegrees
- all the other things internally use double in decidegrees (or radians
in temporaries)
- in pcbnew UI the unit is *still* int in decidegrees
The idea is to have better precision everywhere while keeping the user with int i
angles. Hopefully, if a fractional angle doesn't come in from the outside, everything
should *look* like an integer angle (unless I forgot something and it broke)
When the time comes, simply updating the UI for allowing doubles from the user should
be enough to get arbitrary angles in pcbnew.
- Removed spurious int casts (these are truncated anyway and will break
doubles)
- Applied the Distance, GetLineLength, EuclideanNorm, DEG2RAD, RAD2DEG
ArcTangente and NORMALIZE* functions where possible
- ArcTangente now returns double and handles the 0,0 case like atan2, so
it's no longer necessary to check for it before calling
- Small functions in trigo moved as inline
* Improve the stable and testing build version option logic.
* Use CMake FindPythonInterp to configure the Python interpreter.
* Use Python interpreter to determine the system Python module install
path if not already defined on the command line.
* Add header symbol checks for asinh(), acosh(), and atanh().
* Add test source to check for isinf() which can be defined as a C++template.
* Replace conditional compile on windows systems for aXXXh() with CMake
configuration tests.
* A few minor MSVC compile fixes.
* Fix incorrect python environment string in fixswigimports.py
* Create a separate document for KiCad CMake build options.
* Create a separate how to compile KiCad on Windows document.
Mainly to plot drill maps, but can be used to plot boards, for documentation.
The print svg still exists, but the plot SVG has more options (mirroring, holes in pads),
however print svg allows color print, and full board printing, and plot does not.
