note kyle <blockquote> <c> # # calculate the average, avoiding any division by zero traps # my $avg_cpu_load = $total_cpu_load ? $total_cpu_load / $active_pid_num : 0 ; </c> </blockquote> <p>I'd think if you want to avoid division by zero, you'd need to check the denominator for zero-ness rather than the numerator. That is: <c> my $avg_cpu_load = $active_pid_num ? $total_cpu_load / $active_pid_num : 0; </c> <p>Or am I misunderstanding something here? 559540 559540
