Uncertainties, a free, cross-platform program that handles calculations with numbers with uncertainties (like 9.80±0.03). This is in fact what Pint uses under the hood. The uncertainties package returns its result with an uncertainty as predicted by linear
error propagation theory, while also correctly taking into account correlations between variables.
To install, open up a terminal window from within your Anaconda Navigator distribution and use the pip installer, as shown below:
