|
|
its dimension anymore)

|
|
- Repository file tree cleanup
|
|

|
|
- SI fundamental constants added
|
|
- `q_` prefix applied to all the UDLs (thanks [@kwikius](https://github.com/kwikius))
|
|

|
|
- Project documentation greatly extended and switched to Sphinx
|
|
- A few more usage examples added
|
|
- ASCII-only output support added (thanks [@yasamoka](https://github.com/yasamoka))
|

|
|
- libfmt updated to 6.2.0
|
|
- Added absolute functions and epsilon to math.h (thanks [@mikeford3](https://github.com/mikeford3))
|
|
- Added a lot of prefixes to named units and introduced `alias_unit` (thanks [@yasamoka](https://github.com/yasamoka))
|
|
- Linking with Conan targets only when they exists ([#98](https://github.com/mpusz/units/issues/98))
|
