[HELP] Value range of a returned variable

Hi there, It's me again.
Since I am still simulating a laser fusion melting process, I ran into a completely new problem.
The heat sources I use for my calculations are computed using a UDF.
It looks like this:
DEFINE_SOURCE(sourceterm,c,t,dS,eqn) ...lots of code... return source;
Now here is the thing: the returned variable ("source" in this case) has a limited range. Apparently it seems to be restricted to the range of a signed long integer -2,147,483,648 to 2,147,483,647).
All variables were initialized as "double" and I am running the case in double precision, so the problem is definitely the range of the returned variable.
Now the intensities of a laser beam are very high, so I need higher values of the returned variable.
What can I do?
