Initialize with interval [0,1] and one requested interval.
val mantisse A increasing ordered vector of values representing mantisse values between 1 and 9.

Does the actual scaling.
- Returns:
- Number of intervals after rescaling. This will in the most cases differ from the requested interval number! Always >0.
- Parameters:
-
a Start value after scaling (always >= start) b Stop value after scaling (always <= stop) start Start value stop Stop value ivals Requested intervals
- Returns:
- Number of intervals after autoscaling
If the given interval has zero length the function returns the current interval number and a and b remain unchanged.
