No, The issue is that '/' is always floating point division in haskell, for integer division, use `div`.
1 `div` 0 throws an exception like you expect.
GHC behaves exactly the same as C here. But in C whether '/' means floating point or integral division depends on the types of its arguments, in haskell they are separate operators.
Aha, I was missing something. Indeed, 1.0/0.0 gives me infinity with C. Thanks for the clarification. Python does throw for 1.0/0.0, but I think there's a (not very commonly used) module to turn that off. It might be nice for GHC to have a some way to turn exceptions on, but I can accept getting NaNs, and doing the ieee754 thing by default seems entirely reasonable. But what about that NaN->Integer conversion thing?
