Can python compute ln(640320**3 + 744)/163**.5 to 30 places? I ran across this the other day. It's value is said to be the same as pi to about 30 places. I'd like to know if it is possible to do this in python with numpy. A friend pointed out that the Windows Calculator gives about 30 significant digits. I tried it and got 3.1415926535897932384626433832797. Pi to 32 places is 3.14159265358979323846264338327950, so the calculator is accurate to 31 significant digits (including the 3.). So, how about numpy? Thanks, Dick Moores Win XP Pro Python 2.5 yet to install numpy
