Yes, that´s right but if you have to perform many operations maybe the "echo" + "bc" form is quite faster:

felix@mateina:~$ time echo "24 * 365.25" | bc 8766.00

real    0m0.018s
user    0m0.002s
sys     0m0.001s

felix@mateina:~$ time python -c "x = 24 * 365.25 ; print '%.2f' % x " 8766.00

real    0m0.154s
user    0m0.015s
sys     0m0.007s
felix@mateina:~$ cat /proc/cpuinfo |egrep "(model name|MHz|cache|bogo)"
model name      : AMD Athlon(tm) XP 2000+
cpu MHz         : 1666.922
cache size      : 256 KB
bogomips        : 3335.59

Best regards,

Felix
