Comment:
`unsafeCoerce#` isn't guaranteed to work between integral types and
floating point types, see the documentation:
[http://www.haskell.org/ghc/docs/6.12.2/html/libraries/ghc-prim-0.2.0.0
/GHC-Prim.html#v%3AunsafeCoerce%23].
There should really be a primitive to let you do this - feel free to open
a separate feature request.
