(I'm just a new convertee to the ways of Functional Programming, so
please go easy on me! ^_^;;)

Why is it that `Double's in Hugs only seem to have the same
precision as a `Float'? I've some code here that only iterates a few
hundred times, and the amount of accuracy lost is getting a bit
ridiculous ...

Exactly[0] the same code produces the much more accurate results in
GHCi. I'd switch over, but at the very least I'd like to know why
this is happening.

BTW: From the description at
, I seem to get the impression that should only
be used for announcements, yet the archive shows quite a bit of
general discussion going on. Should I have posted this to the
aforementioned list as well / instead?

[0] Minus the non-Haskell 98 compliant bits, like the missing
fromInt ... -_- Took me a while to figure that one out.
