KISS MY ASCII GOOD PI!

[Pete]

Interesting to note that with both string math routines, Treebeard's and mine, pi to 28 digits and 36 digits is incorrect by over 1 on the last digit, and I don't see it as a rounding situation. All other iterations of 10 to 150 appear to be correct, except these. So to correct this, both routines would have to lengthen the value of the square root of 8. I did that by an extra 20-digits, and it fixed the aforementioned discrepancies. Nice; however I wonder what the accepted value of the square root of 8 is for mathematicians who have worked with this formula?
