Hi All,
Attached is a patch for adding a new significant figures parameter to the normal output format. Somes when using large I/O sizes, the hardcoded 4 sig figs does not truly represent the throughput, due to rounding/truncating. So this parameter allows the value to be user settable, without having to inspect json outputs (intended for machine readable, not human readable). With this patch, the default behavior is exactly as it is today, meaning the default sig_figs is 4. If a user enables --sig_figs=5, then one extra digit will be displayed. Please let me know of any bugs/issues. Thanks.
Regards,
Jeff
