Haskell Integers are not a proper subset of Haskell Floats or
Doubles.  Haskell does not support real numbers.

It's a similar problem with C/C++.  The "long" type is almost never
a proper subset of "float", but C will nevertheless happily convert
it for you without you asking, potentially losing precision in the
process.
