> I think it’s important to at least know that these fundamental operators exist. And some inkling of what they're good for. I have that too, although I'd have to look up the exact syntax of the operators (i.e. even what symbols they're actually written as) in pretty much every language I know that has them. Heh, look up if it has them to begin with... > Also, whenever I see code that takes a number, converts it to string, does some manipulation and then converts back to number, I always assume that this was a quick hack It's usually the other way around, IME: You get what should be a number as a string, have to clean it up (thousands separators, different decimal "point" (comma, dammit!) symbols, etc), convert it to a number to do some calculation, then apply the formatting back onto the result.
