<p style="color: grey"> Python recipe 577124 by <a href="/recipes/users/4172944/">Steven D'Aprano</a> (<a href="/recipes/tags/comparisons/">comparisons</a>, <a href="/recipes/tags/distance/">distance</a>, <a href="/recipes/tags/math/">math</a>, <a href="/recipes/tags/maths/">maths</a>, <a href="/recipes/tags/numeric/">numeric</a>, <a href="/recipes/tags/string/">string</a>). </p> <p>Generic "approximately equal" function for any object type, with customisable error tolerance.</p> <p>When called with float arguments, approx_equal(x, y[, tol[, rel]) compares x and y numerically, and returns True if y is within either absolute error tol or relative error rel of x, otherwise return False. The function defaults to sensible default values for tol and rel.</p> <p>For any other pair of objects, approx_equal() looks for a method __approx_equal__ and, if found, calls it with arbitrary optional arguments. This allows types to define their own concept of "close enough".</p>
