JUnit3FloatingPointComparisonWithoutDelta

JUnit 4's floating-point overloads of assertEquals(expected, actual) always throw an exception, and some floating-point calls to JUnit 4's assertEquals do not even compile.

To continue comparing floating-point numbers using Double.equals semantics, you may be able to cast one argument to Object or use Truth's assertThat(actual).isEqualTo(expected) / assertWithMessage(message).that(actual).isEqualTo(expected).

Alternatively, you can switch to tolerance-based equality testing, which changes your code's behavior for negative zero (in JUnit and Truth) and for infinities and NaN (in Truth). If you want that, use JUnit's assertEquals(expected, actual, delta) or Truth's isWithin(...).of(...), possibly with a tolerance of zero.
