Added dim_angle, Angle concept etc.
Not really for merging, but fun to play with.(The main problem is that it doesnt conform to SI)
See https://github.com/mpusz/units/issues/99
Could try adding degrees etc in same way as non-si units
examples, clcpp_response,alternative_namespaces::clcpp_response : use fmt functions for showing precision of quantities
examples, alternative namespaces : combined the alternative namespace quantity typedefs in header files.
examples, alternative namespaces : add simple timer example
new namespaces are
international ( combination of us and imperial + Canada etc)
iau (https://www.iau.org/
imperial ( old imperial units)
typographical ( for sizes of printing fonts etc)
These namespace are based on some research , mainly on wikipedia.
Look in src/include/units/physical/si/length.h to see links to see the references to documentation justifying the change.
Unfortunately there are 3 foot units for example, an old imperial version, an old us version and an international version, which is more recent and attempts to unify the two previous ones. All versions have slight changes in value, so I opted to use the international version
The main change in the layout is that inch,foot and yard have been moved from us to international.
With this modification, I also modified the physical/us/area.hpp, volume.hpp and volume.hpp headers to refer to the international units.
This may not be correct, but if the modified us::foot (rather than international foot is used as a basis for these units, then
there is a ratio integer overflow during compilation, probably due to taking 3rd power of a ratio. After this commit. I will try to show that on another branch.
Add si::density quantity header .
Add si::resistance quantity header.
Update si::capacitance header with mF, uF, nF, pF.
Update si::voltage header with mV, uV, nV,pV
Third party example : add capacitor time curve example
Add incoherent length units, TODO move them out from si header.
Third party examples : add clcpp_response showing effectivenes of typed units for physical quantity library
Third party examples : add conversion factor example
Add third party examples to cmake
Third party examples : box example : Add air_density constant for clarity remove explicit this-> and tidy up.
Third party examples : in clcpp response example, change base unit from km to m for single type or all units example.
Third party examples : conversion_factor , add inline constexpr to units_str function.
Third party examples : box_example, change quantity::unit syntax to quantity::unit<> to allow generic(default double) value_type.
examples : remove examples from third party to main examples directory. Update cmake.
physical/si/resistance.hpp : remove underscores from kiloohm etc, UDL collision with 'R' so prefix with underscore
