weird interaction with native round() function about numericalunits HOT 1 CLOSED

From the README:

To express a dimensionful quantity in a certain unit, divide by that unit, e.g. when you see my_length / cm, you pronounce it "my_length expressed in cm".

So if you want to know "what is vi expressed in uL", you need to do print(vi / uL).

See also the part of README that says:

Unit errors, like trying to add a length to a mass, will not immediately announce themselves as unit errors. Instead, you need to run the whole calculation twice (in a new Python session each time). If you get the same final answers both times, then congratulations, all your calculations are almost guaranteed to pass dimensional analysis! If you get different answers every time you run, then you made a unit error! It is up to you to figure out where and what the error is.

If you tried this you would notice that the 1.5168342577649152e-10 is randomly-varying and therefore not the right answer to your question.

round has nothing to do with this.

Hope that helps.
