This is the uncertainties Python package, which performs transparent
calculations with uncertainties (aka "error propagation"):
>>> from uncertainties import ufloat >>> from uncertainties.umath import * # sin(), etc. >>> x = ufloat(1, 0.1) # x = 1+/-0.1 >>> print 2*x 2.00+/-0.20 >>> sin(2*x) # In a Python shell, "print" is optional 0.9092974268256817+/-0.08322936730942848
This package also automatically calculates derivatives of arbitrary functions:
>>> (2*x+1000).derivatives[x] 2.0
The main documentation is available at https://uncertainties.readthedocs.io/.
The release branch is the latest stable release. It should pass the tests.
master* branches in the Github repository are bleeding-edge, and do not
necessarily pass the tests. The master branch is the latest, relatively
stable versions (while other master* branches are more experimental).
Other branches might be present in the GitHub repository, but they are typically temporary and represent work in progress that does not necessarily run properly yet.
