awesome-modern-cpp VS polars

seriously, don't bother with c++. it will become irrelevant eventually.

but if you choose to ignore my advice, check[0] these[1]

I can't recommend a course in c++, but check out Awesome Modern C++

1) Some collections of interesting stuff are sometimes under "awesomexyz" on github. ( the one I included here probably isn't the _best for someone new to C++ but I'm including it anyway) * https://github.com/rigtorp/awesome-modern-cpp

https://awesomecpp.com/ compiled list of c++ resources, only be aware of these no need to crunch through all

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-...).

That turned out to be related to pola-rs/polars#11912, and this linked comment provided a deceptively simple solution - use PARSE_DECLTYPES when creating the connection:
