measure{:.python} is a library for unit-of-measure types.
- models unit-of-measure types such that there is form equivalence.
Consider temperature, which is measured in units of Kelvin, Celsius, or Fahrenheit.
Theoretically, ...
We have
temp = Temperature.from_fahrenheit(80.9)
equivalence = temp.as_celsius() == approx(temp.as_fahrenheit()) == approx(temp.as_kelvin())
assert equivalenceAnother example, for the complex numbers:
This is useful, because it enables abstraction from the unit to the underlying measure.
Consider these additional examples:
- Rotation - over angle or radians
- Graphical distance - over px, pt, em, etc...
- unit validation via symbolic expressions (time permitted)
It implements the Measure{:.python} type
