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. Change-Id: I01100d600515e16df58ce508b50982ffd762cc49	10 years ago
