function assertAlmostEquals
assertAlmostEquals(
actual: number,
expected: number,
tolerance?,
msg?: string
): void
Deprecated

(will be removed after 1.0.0) Import from https://deno.land/std/assert/assert_almost_equals.ts instead.

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.

Examples

Example 1

import { assertAlmostEquals } from "@std/testing/asserts";

assertAlmostEquals(0.01, 0.02, 0.1); // Doesn't throw
assertAlmostEquals(0.01, 0.02); // Throws
assertAlmostEquals(0.1 + 0.2, 0.3, 1e-16); // Doesn't throw
assertAlmostEquals(0.1 + 0.2, 0.3, 1e-17); // Throws

Parameters

actual: number
expected: number
optional
tolerance
optional
msg: string

Return Type
