Re: [Amforth-devel] Float testing - small/large numbers

Leon,
I think there is an issue with negative numbers:

> -1 s>f fconstant _-1    >>>> define 1.0
ok
> 1 s>f fconstant _1      >>>> define -1.0
ok

> _1 _pi f* _1e4 f* f>s .    >>>> 1.0 * pi * 1.0E4 = 31415
31415  ok

> _-1 _pi f* _1e4 f* f>s .   >>>>> -1.0 * pi * 1.0E4 = -31426
-31426  ok

It cannot be caused by of a rounding error accumulating or loosing a
valid digits. Some minor bug somewhere..
