Hello, Is there a pure Haskell implementation of Floats, i.e., one that (unlike GHC.Float) doesn't use foreign calls for things like isFloatNegativeZero? I don't care about performance; I'm just looking for something that doesn't use foreign calls.

Huh, what's the use case?

I'm implementing a compiler that doesn't support foreign calls (yet).

Cheers, Tim

There's the numbers package which contains BigFloat. You can pick your own precision, but it's not IEEE. It's actually base 10 floats which makes it more fun (actually, the iEEE standard will cover base 10 floats in the future). -- Lennart On Wed, Jan 21, 2009 at 12:44 AM, Tim Chevalier wrote:

Yes (with the integer-simple library -- I was hoping there was some analogue of integer-simple for Float, although Don didn't think there was one).
