      There is an unnecessary and very expensive amount of data conversion going on here. First we convert our CSV into an iterator of DataFrames, then those DataFrames are converted into Python data structures compatible with SQLAlchemy. Those Python objects then need to be serialized in a way that’s compatible with the database they are being ...

      Just as in Python and Java, the result of a math operator is cast to the more general or precise datatype. uint64 + uint16 => uint64 float32 / int32 => float32 Warning: upcasting does not prevent overflow/underflow. You must manually cast first. Use case: images often stored as uint8. You should convert to float32 or float64 before doing math. 34

      Step 3: Convert any percentage to a decimal for q. We are looking for the number where 30 percent of the values fall below it, so convert that to .3. Step 4: Insert your values into the formula: ith observation = q (n + 1) ith observation = .3 (40 + 1) = 12.3 Answer: The ith observation is at 12.3, so we round down to 12 (remembering
