<p style="color: grey"> Python recipe 535164 by <a href="/recipes/users/1963659/">sasa sasa</a> (<a href="/recipes/tags/algorithms/">algorithms</a>). </p> <p>This class permits full error propagation for numeric values. It wraps a value and an associated error (standard deviation, measurement uncertainty...). Numeric operations are overloaded and permit use with other Uncertain objects, precise values without errors, generally speakin gmost other numeric (even array) objects. The "traitification" can easily be reverted by dumping all references to traits.</p>
