Thank's for your replies so far. sprintf() is the way to do it (now I see
that my problem was not very tricky [I take the blame on me]).

So I looked into djgppstd.h for [efg]convert but didn't find them. Instead I
found these entries:

char*     ecvt(double, int, int*, int*);
char*     fcvt(double, int, int*, int*);
char*     gcvt(double, int, char*);

Just a guess, but wouldn't it make sense to remove these lines (to avoid
confusion for people like me)? Or what is the reason that they are still
alive?

Thanks for reading, in confusion,
