It’s useful to point out pitfalls of lower precision too. I don’t usually see these articles go over that.
Operations on a few million rows of float32s can give strange results. For example when summing. Df[“colA”].sum() can be fairly different than df.sort_index()[“colA”].sum(). It’s a trap for the unwary.
