I couldn't find anything about "Dutch rounding". Isn't rounding exactly
defined? 0.1-0.4 round down -> 0.0, 0.5-0.9 round up -> 1.0?

MS state that rounding is dependent on the internal binary
representation of the number and thus VarRound doesn't always get it
right, i.e. you can't tell with any cert

Now I'm confused. I'm adding more types to VarRound and I'm also implementing
the test_VarRound function (programmer

I just saw that I submitted a patch with some debug code in it. I guess I'll
have to send it again anyway :)

I didn't mean that I never tested it. Of course I had a test program with which
I found out what results Windows wou
