Yes, the 5000 decimal places (5001 digits) of pi are correct. Except that haxial stops at ...4132604721, and the next 10 digits are ...5695162396..., so it should round that up (or add more digits until it only rounds down). The lack of functions for it limits its use, though. I mean, does anyone need 1+1 to be accurate to10000 digits? Except for pi and e, everything you could possibly produce could be stored as a big fraction. Which would, actually, be a lot more useful. sin, cos and tan would help, though ;)
