I'm using the great quantities package for Python. I would like to know how I can get at just the numerical value of the quantity, without the unit.
I.e., if I have
E = 5.3*quantities.joule
E.item() seems to be what you want, if you want a Python float.
E.magnitude, offered by tzaman, is a 0-dimensional NumPy array with the value, if you'd prefer that.
The documentation for
quantities doesn't seem to have a very good API reference.
