PS: I prefer a no-*printf() solution on inner loops for speed, and just memcpy() the bytes of "0.0000*" I need to the buffer, or often even better, fwrite() or write() first the "0.0000*" bytes out and then the fps, so there is no excess copying. The idea of parsing the "%.*s%s" over and over bothers me. Maybe the optimizers chew it up? Output is, after all, the point of the exercise. Work back from output to the minimum variables you need. Write stuff in pieces if pieces is how it comes. However, write() is a system call where you can lose the CPU, so the FILE* buffering of fwrite() is a good thing for little pieces. And putc() is a macro, so it is always inline optimizable.
