Every other language throws an exception, even C will crash the

what about this note in Control.Exception:
That's just not true. It depends on how your system (compiler?) is
configured, but the default on most systems that I've used is to
return NaNs.
It's how the system FPU is configured; most FPU hardware on Unixlike
systems let you configure the FPU behavior on a per-process basis,
although the amount of configurability may vary.
That said, the divide by zero exception you get in both C and Haskell
is *integer* divide-by-zero. Floating is mandated by IEEE standard to
produce Inf (but as said above, can usually be configured).
