Probably, the source of a `bug' is a language agreement that the input is in decimal representation (`0.9') and its meaning is a floating approximation in _binary_ representation.
What are you talking about? Input in decimal representation is stored as a Rational number. There is absolutely no loss of precision.
No need for whatareyoutalkingabout preamble. Input in decimal representation *in general* is stored as the implementors wish. You can't a priori know all, if you are far from the implementors, and if the relevant documentation is hard to find... How many people on this mailing list are really au courant?
I apologize for the preamble. But the Haskell spec still clearly specifies that numeric literals are "stored" as Integer if they lack a decimal point and Rational otherwise. And the fromInteger/fromRational is applied to this. For Haskell there is no implementors choice if you want to obey the report. -- Lennart
