No, this is right. The calculation takes practically no time; on my system, it takes some 10 ns. The uncertainty of the timeit result is at least a few hundred nanoseconds.
There are more than 100000 multiplications to perform on a soaring size integer. I have some doubts "x=123456**123456 " only takes 10 ns on your system. On my computer it takes roughtly 4 s, mesured with a watch. I can't do "len(str(x))" to know the size, I have to kill the process But x.bit_length() answers 2088091, so x should have about 600000 digits If I measure execution time:
t=time(); x=123456**123456; print(time()-t)
0.0 There is still something wrong I suppose that my computer CPU goes to 100% busy and that the timer used by timeit or time no longer works. -- https://mail.python.org/mailman/listinfo/python-list
