I am developing a trading system which stores data in SQLite, consisting of OHLC and volume. I would also like to store some indicators like RSI etc I read the other answer which indicated integers as the data type. In my case I am looking at 8 digit precision which would slow down the calculations if I were to multiply every value by 1e8 Any recommendations are appreciated!

Workaround 1
The trick of using an
