function assertAlmostEquals
import { assertAlmostEquals } from "";

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.


Example 1

import { assertAlmostEquals, assertThrows } from "";

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));


actual: number
expected: number
tolerance = [UNSUPPORTED]
msg: string
