RE: [Haskell-cafe] Error with Float

Opps, its 0:f t not 0:: f t and the same for 1:f (t-1)

From: "Dinh Tien Tuan Anh" To: haskell-cafe@haskell.org Subject: [Haskell-cafe] Error with Float Date: Tue, 19 Jul 2005 14:48:55 +0000

This is my function to convert a fraction (0

f x Št<1 = 0::f t Šotherwise = 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
