Like sos2U but no underflows are reported.
Like sos2U but no underflows are reported. Instead the values are first clamped to be in range so in the event value < min, return a tuple representing the min.

When value < min, an underflow key-value pair is emitted. This controls the key that is emitted.
When value is missing, a separate key-value pair is emitted. This controls the key that is emitted.
sos2 binned value
This is the purest form of sos2 binning that clamps the values in the [min, max] interval and then bins.

When value < min, an underflow key-value pair is emitted. This controls the key that is emitted.
When value is missing (None), a separate key-value pair is emitted. This controls the pair(s) that is/are emitted.

sos2 binned value
Sos2 takes a value and breaks it apart into a linear combination of the two closest values as specified by the min, max, and delta. As long as the value being sos2 binned exists in the interval [min, max], then there exists an isomorphism between the value and the sos2 binned value.
