- a couple of fixes like this one:
- fprintf(f, "%g", real); + fprintf(f, "%g", static_cast<double>(real)); with 'real' being a fouble object. as fprintf is a c function with variable arguments one cannot pass non-primitive objects through it and there is no way for the compiler to figure out the right conversion operator, so we give it a helping hand :)
