This is a package used to experiment with adding unit propagation to QuantiPhy. It currently employs simple-minded simplification rules that are relatively easy to fool. Also, there is a strong emphasis on simple electrical unit scenarios. Even so, it shows promise for use in well controlled settings.

Here is simple example:

from unit_propagation import (
    UnitPropagatingQuantity as Quantity, QuantiPhyError
)
try:
    v = Quantity("2.5V")
    i = Quantity("100nA")
    print(v/i)
except QuantiPhyError as e:
    print(f"error: {e!s}")

Included in the package is a simple RPN calculator that allows you to explore the capabilities and limitation of the unit propagation.
