> If the StepNormalizer is used in MULTIPLES mode, and a normalized point is very close to the last point (for instance the start time), then it may be rounded to the same point as the previous point. This is because 1 + e = 1, where e <= machine epsilon. This results in output being given twice for the same point. I made a small patch to avoid this from happening.
