[TestFixture]

public class FloatsTest
{
    [Test]

    public void FloatsAreEqual()
    {
        var comparer = new FloatEqualityComparer(10e-6f);

        var actual = -0.00009f;

        var expected = 0.00009f;

        Assert.That(actual, Is.EqualTo(expected).Using(comparer));

        //Default allowed relative error 0.0001f

        actual = 10e-8f;

        expected = 0f;

        Assert.That(actual, Is.EqualTo(expected).Using(FloatEqualityComparer.Instance));
    }
}
