function assertAlmostEquals
import { assertAlmostEquals } from "https://dotland.deno.dev/x/justaos@v0.1.3/test.deps.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.

import { assertAlmostEquals, assertThrows } from "https://deno.land/std@$STD_VERSION/testing/asserts.ts";

assertAlmostEquals(0.1, 0.2);

// Using a custom tolerance value
assertAlmostEquals(0.1 + 0.2, 0.3, 1e-16);
assertThrows(() => assertAlmostEquals(0.1 + 0.2, 0.3, 1e-17));

Parameters

actual: number
expected: number
