View source for Talk:Almkvist-Giullera formula for pi

===Julia answer for Pi is wrong===
After spending several minutes trying to figure out why my Wren entry was disagreeing with Julia, it turned out that the latter is wrong - Python, REXX and an independent source all agree on this - though, looking at the code, I couldn't see anything obviously wrong. --[[User:PureFox|PureFox]] ([[User talk:PureFox|talk]]) 10:56, 12 October 2020 (UTC)

Ah, it turns out setprecision() takes an argument in significant bits, not decimal digits! Thanks for the comment, fixed. --[[User:Wherrera|Wherrera]] ([[User talk:Wherrera|talk]]) 19:08, 12 October 2020 (UTC)

:I wondered whether it might be something like that when I added the Go solution where you also have to estimate how many bits of precision you need for a given number of decimal places. Anyway, glad you've fixed it now :) --[[User:PureFox|PureFox]] ([[User talk:PureFox|talk]]) 20:47, 12 October 2020 (UTC)

== Divide by zero error in big.wren; shouldn't there be a little more robust error-handling in the big.wren Library? ==
