code: static public void assertEquals(String message, float expected, float actual, float delta) {
      		if (Float.compare(expected, actual) == 0)
      			return;
      		if (!(Math.abs(expected - actual) <= delta))
      				failNotEquals(message, new Float(expected), new Float(actual));
      	}
docs: Asserts that two floats are equal concerning a positive delta. If they
  are not an AssertionFailedError is thrown with the given message. If the
  expected value is infinity then the delta value is ignored.
