Code:
temp2 = ceil((temp / 34));
printf("%d | %d", temp2, temp);

It prints out "0 | 13", "1 | 13" would be right.
Another time it prints out "1 | 45", "2 | 45" would be right.

Does somebody know where my fault is?

C/C++ integer division doesn't round. It truncates.

So it becomes essentially
Code:

temp2 = ceil((0));
printf("%d | %d", temp2, temp);


Assuming temp is an integer.

check this out http://codepad.org/R5CZ4sc0

EDIT: I hope you notice the 34. <- that's 34DOT
Or you could just type 34.0
