String.to_integer/1 why no exclamation mark?
Surely this has been asked and explained before, but for some reason I couldn’t find it.
stringmust be the string representation of an integer. Otherwise, anArgumentErrorwill be raised.
If an exception is a possibility and there is a convention of marking such functions with a trailing exclamation mark in the name, why doesn’t this function have it?
Thanks!

Because there is no non-raising analog function with the same name. If you take a closer look, all bang functions have their analogs without bangs.
FYI, If you want to handle parsing error, use Integer.parse
