<< Digits. Feh. What a waste of chips and neurons. Sure seems that way to me. If anyone can please explain what the big deal is, I'm listening. —Dan

Digits. Feh. What a waste of chips and neurons. The only excuse: Now that they've done it, converting to the continued fraction might be slightly easier than extracting the cf directly. But if you want both, it might be easier to extract the decimal from the cf. Or maybe not, since they probably wrote their own multiprecision routines to use base 10^19 vs 2^64 to dodge the big radix conversion cost. Or is floating point still so much faster than fixed that they sacrificed several digits per "word" to redundant exponents, like the old Mersenne finders? --rwg

They made a new computation record of Pi,

22 459 157 718 361 digits.
This is big.
the digits seems to be rather normal in base 10 and 16.

also : 22.459157718361 is Pi^E.
