i wrote a simple program of evaluating Pi number in M6 to test cpu
computation timing, to do this a simple for loop
x=0;For[i = 1, i < 10,000,000, i++, x = x + 1/(i^2)];N[Sqrt(6*x),25]//
the result was catastrophe! it take few minuates. but i first expect
to do this very simple job in few
seconds.computation time is just satisfactory up to 100000 cycle.
could anyone interperet this falut?
our get an idea to improve the result?
