import { assertAlmostEquals } from "https://deno.land/std@0.222.0/assert/mod.ts";
Make an assertion that actual and expected are almost equal numbers
through a given tolerance. It can be used to take into account IEEE-754
double-precision floating-point representation limitations. If the values
are not almost equal then throw.

assertAlmostEquals(0.1 + 0.2, 0.3, 1e-16); // Doesn't throw
assertAlmostEquals(0.1 + 0.2, 0.3, 1e-17); // Throws
