There's no conversion function in CPLEX that I'm aware of. When working with binary variables (in the Java API), I usually loop through them with the logic "if x < 0.5 then y = 0 else y = 1" rather than using the rounding function. I haven't checked to see which is faster, since it typically doesn't matter: the time extracting the solution is negligible compared to the time finding the solution.

Thank you for the quick response...
I did think about that...I was hoping there would be a function for Int2Int... ;)

Loop through the returned array of doubles, rounding each entry and then casting it to int.

Hello,
I need to copy a 4D matrix solution dvar boolean into a 4D int in C++, and then solve again.
I found the getValues functions in IloCplex that might work, but there is no case where both members of the functions are Integer Arrays...
any suggestions?
Thank you in advance! :)
