- 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 :)
