    public @NotNull DoubleAssert isEqualTo(double expected, Delta delta) {
      return isEqualTo(expected, delta.value);
    }
docs: Verifies that the actual {@code Double} is equal to the given one, within a positive delta.
  
  @param expected the value to compare the actual one to.
  @param delta    the given delta.
  @return this assertion object.
  @throws AssertionError if the actual {@code Double} is not equal to the given one.
  @deprecated use method {@link #isEqualTo(double, org.fest.assertions.Delta)} instead. This method will be removed
