Package: bc Version: 1.06.94-3 Severity: normal If you have a multi-core CPU (as Intel Core2 Duo) and use bc to calculate something, only 1 core is used. Try this:
$ echo "scale=5000; 4*a(1)" | bc -l This function will calculate "Pi (3.14159...)" with 5000 decimal precision. In my machine is necessary 38sec to finish. In meantime, use "top" (and press '1') to see CPU usage. You will see that CPU0 go to ~99% and CPU1 go to ~1%. I think that if *all* cores is used, time decrease to a half! Best regards, Renato S.
