Which languages did you try? I found that dividing 1.0 by 0.0 gives Infinity in Java, C, Julia, JavaScript, Ruby, Clojure, Haskell and Rust. I get division errors in Python and Perl. Curiously, Go gives me a compiler error if I divide constant literals, but assigning 0.0 to a variable and dividing by it does work. On top of that, assigning -0.0 to a float variable leads to it having the value +0.0, which I would call a borderline compiler bug. Both are probably a consequence of Go constant literals not being IEEE-754 floats but some arbitrary precision number types, but it's very unexpected behavior.

  Python does throw an exception but C# does not.

  Dividing 1.0 by 0.0 gives ∞ in C# as well when I try it.

    You're right. I must've divided 0 by 0 and -0. That's the only way C# gives me NaN. I thought I'd specifically avoided doing that.
