[Haskell-cafe] Error with Float

This is my function to convert a fraction (0<x<1) to binary :
¦t<1 = 0::f t
¦otherwise = 1::f (t-1)
where t = 2*x
I guess there's nothing wrong with that, but when traced, it has something
like 0.6*2 - 1 = 0.600001
This error got accumulated and made my f function wrong (will eventually
evaluate an infinite 0, no matter what value of x)
Please tell me there's some ways to deal with that.
Thanks a lot
