I wonder why Infinity has a sign in IEEE floating processing, as well as 0. To support this behaviour uniformly one would need a +0 or -0 offset for each number, which would lead straightforward to non-standard analysis ... Prelude> 1/0.0 Infinity Prelude> -1/0.0 -Infinity Prelude> -0.0 -0.0 Prelude> 1.0-1.0 0.0 Prelude> -(1.0-1.0) -0.0 Thus (a-b) is not the same as -(b-a) for IEEE floats! _______________________________________________ Glasgow-haskell-users mailing list [EMAIL PROTECTED] http://www.haskell.org/mailman/listinfo/glasgow-haskell-users
