------------------------------------
Summary: PlaneAngle normalize fails for very small numbers.
Key: NUMBERS-94
URL: https://issues.apache.org/jira/browse/NUMBERS-94
Project: Commons Numbers
Issue Type: Bug
Reporter: Matt Juntunen
When the {{PlaneAngle.normalize()}} method is called to normalize between 0 and 1 turns and is passed a very small number compared to the 1, then the method returns a number exactly equal to the angle upper bound. This breaks the API contract since the return value must be strictly less than the upper bound. Ex:
{code:java}
PlaneAngle angle = PlaneAngle.ofTurns(-1e-18);
double normalized = angle.normalize(PlaneAngle.PI).toTurns();
// normalized is equal to 1 but it should be 0 since 1 - 1e-18 = 1, which is equivalent to 0 in turns)
{code}
