[Mono-devel-list] problems wih decimal on cygwin

[Konstantin Triger]

Hi Eno,

I think not:
In the reported bug mono divides exactly, while in .Net the result is 
rounded.
I have a situation when the result is wrong (0/x != 0) and an exception 
is thrown. When I test it with mono 2.0 it works correctly. I also 
suppose that on linux the issue will disappear.

Regards,
Konstantin Triger
