Re: [Haskell-cafe] Accuracy of Data.Number.Fixed

This does not seem right to me:

Prelude Data.Number.Fixed> read "4.00" :: Fixed (EpsDiv10 (EpsDiv10 Eps1)) 4.00 Prelude Data.Number.Fixed> read "4.01" :: Fixed (EpsDiv10 (EpsDiv10 Eps1)) 4.00 Prelude Data.Number.Fixed> read "4.02" :: Fixed (EpsDiv10 (EpsDiv10 Eps1)) 4.03 Prelude Data.Number.Fixed> read "4.03" :: Fixed (EpsDiv10 (EpsDiv10 Eps1)) 4.04 Prelude Data.Number.Fixed> read "4.04" :: Fixed (EpsDiv10 (EpsDiv10 Eps1)) 4.05

Why not just use Data.Fixed from base?

import Data.Fixed read "4.02" :: Fixed E2 4.02
