Bjoern Rabenstein 1ca7f24137 Remove float diff tolerance altogether.

Bjoern Rabenstein d742edfe0d Fix precision loss. 
Large delta values often imply a difference between a large base value
and the large delta value, potentially resulting in small numbers with
a huge precision error. Since large delta values need 8 bytes anyway,
we are not even saving memory.

As a solution, always save the absoluto value rather than a delta once
8 bytes would be needed for the delta. Timestamps are then saved as 8
byte integers, while values are always saved as float64 in that case.
