Rounding/truncating numbers across Windows, Linux, Solaris

I am currently working on an application that runs on Windows XP SP2 with .NET 2.0, Linux 2.4.19-16mdkenterprise and Solaris 5.9. The language is C++.

When I compare the output numbers, Windows rounds the numbers up (for example: 13030.65 becomes 13030.7 - precision is 6) and in Linux/Solaris the number is rounded down or more likely truncated (for example: 13030.65 becomes 13030.6).

I can set the precision on the ostream or output file so that the numbers output the same, however, I would like to know of a way to have each platform round the numbers the same.

Is there is a magic bit or some way to make each platform behave the same when rounding/truncating numbers?

Could you post the code which is creating the numbers, noting all places where you assume rounding is occurring?
