Top 6 dataframe-library Open-Source Projects

  • polars

    Dataframes powered by a multithreaded, vectorized query engine, written in Rust

    • Project mention: Why Python's Integer Division Floors (2010) | news.ycombinator.com | 2024-02-28

    This is because 0.1 is in actuality the floating point value value 0.1000000000000000055511151231257827021181583404541015625, and thus 1 divided by it is ever so slightly smaller than 10. Nevertheless, fpround(1 / fpround(1 / 10)) = 10 exactly.

    I found out about this recently because in Polars I defined a // b for floats to be (a / b).floor(), which does return 10 for this computation. Since Python's correctly-rounded division is rather expensive, I chose to stick to this (more context: https://github.com/pola-rs/polars/issues/14596#issuecomment-...).
