Hi all!
I'm working in a project in visual c++ 6.0 with the console application and I want to ask you how to create a program that has portability to work in both platforms, windows and linux.
Another thing, which function we use to round a double to the nearest int number?
Thanks,

Write 100% standard C++, or conditionally compile two different programs customized for the two operating systems.

You'll need to write it yourself, or use a clever workaround. Alternatively, if all you need is to print the rounded double, any formatted output option will do it for you (which opens up ideas for those clever workarounds I was talking about).

I'm here to prove you wrong.

Not bad, but where you say
Personally, I prefer
(floor(dAUX) - dAUX) < (ceil(dAUX) - dAUX), I think you mean (dAUX - floor(dAUX)) < (ceil(dAUX) - dAUX).Personally, I prefer
floor(dAUX + 0.5), if I want to always round .5s in the positive direction. All my posts may be redistributed under the GNU Free Documentation License.

fabs(floor(dAUX) - dAUX)) < fabs(ceil(dAUX) - dAUX)•
