Hello all, I was playing around with the function PrimePi[] and trying different arguments. When I tried PrimePi[10^15] I got the error message saying that the argument is too large for this implementation. I know that it is a large number.! When I use 10^14 as the argument I get an answer, it takes a while but I get an answer. I tried this on a PC running Vista Home Premium 64-bit with Mathematica 6. Then I tried the same thing under Windows XP 32-bit. There was no difference, I got an answer for 10^14 and same error message with 10^15. My question is: I thought that with a 64-bit computer I could use larger numbers.! Maybe I am misunderstanding something here, so please help me understand J Thanks, Robert Robert Pigeon
