WebJan 20, 2015 · Floating point values contain limited precision, which results in their being unable to exactly represent some values, and for errors to accumulate with repeated computation. As a result, it is common advice to only use an equality comparison in very specific situations. WebFor finite values, isclose uses the following equation to test whether two floating point values are equivalent. absolute ( a - b) <= ( atol + rtol * absolute ( b )) Unlike the built-in math.isclose, the above equation is not symmetric in a and b – it assumes b is the reference value – so that isclose (a, b) might be different from isclose (b, a).
