> obviously When we map date range to double range, the length of range is stretched. This stretch introduces error when we compute `length(rangeA)/length(rangeB)` for example, we map date rangeA1 (19900101, 19910101) to double rangeA2(19900101.0, 19910101.0). map date rangeB1(19900101, 19900201) to double rangeB2 (19900101.0, 19900201.0) rangeA1/rangeA2 = 1/12 rangeB2/rangeB2 = (19900201-19900101) / (19910101-19900101) = 100 / 10000 = 1 / 100 -- This is an automated message from the Apache Git Service.
