==Weaknesses of initial VB.NET algorithm ==

Just noting where improvements could be made...<br/>

1. Depends on BigIntegers, which start consuming a considerable amount of memory as the number of digits escalates.<br/>

 

:At heart, it appears to be the same algorithm as my Phix entry, just "de-generalised". --[[User:Petelomax|Pete Lomax]] ([[User talk:Petelomax|talk]]) 23:45, 12 October 2020 (UTC)

==What is a number?==

The task description should be more specific regarding meaning of number. Perhaps including example test cases and output. Presumably the number should not be negative. Should the output include the decimal point when and where appropriate? I'd suggest testing 2, 0.2 and 10.89, with output showing decimal point correctly. With √2 to 480 or 500 decimal places or integers.--[[User:Nigel Galloway|Nigel Galloway]] ([[User talk:Nigel Galloway|talk]]) 15:38, 14 October 2020 (UTC)

: spigot_sqrt(pi_to_100dp), squared, to 100dp? - not sure how much of a stress test that really is.. (my maths is so crap I expected the root would have to be accurate to maybe 200dp, or at least 150dp, but apparently not.) --[[User:Petelomax|Pete Lomax]] ([[User talk:Petelomax|talk]]) 14:59, 15 October 2020 (UTC)
