Python Question
Eliminate units when using quantities for Python
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
I would like to get at just the 5.3. I know I can simply divide by the "undesired" unit, but hoping there was a better way to do this.
Answer
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.
