Arbitrary Precision

[jack]

every now and then someone asks about high precision arithmetic/math functions to be used in QB64, I came across a package that's in 4 includes http://www.hvks.com/Numerical/arbitrary_precision.html, here's the license

so as long as you don't want to sell your programs that incorporate this code you are good to go
I have tested the code a bit in g++ and it seems OK, it should be possible to call it from QB64, and there's no need to compile to a library for you to use it, the only thing you need to be aware of is to link against gomp via -lgomp (it stand for gnu open mp)

Well, like the old Tonight Sow gag, when Johnny Carson was running the sow... How high is it?

Pete

[jack]

Pete, do you mean how high is the precision?
I have not tested it much but I ran the pi_brent_salamin to 100,000 in less than 8 seconds, that's clearly not the fastest but it's not too bad

I checked out the website.  "How high is it?"

Well over 'my' head... lol

I am glad that we have clever people, like you guys, when it comes to understanding this stuff.

Three puffs, two snorts, and eight chugs high!

[johnno56]

Not sure of the meaning of that... lol  But at least it does to someone, right? lol

Three puffs of weed, two snorts of coke, and eight shots of whiskey!  I’ll leave to to you to decide “how high is that?”  ;D

I suppose I could program String Math could do 100,000 digits, but I'd have to party all night at Steve's house to be motivated enough. Nay, I probably be to too strung out to do it.

believe it or not, the author of the afore mentioned bignum routines uses C++ string to store the number, not only that but as far as I can tell he uses base 10
it could be significantly faster if he used a larger base like 10000

[Pete]

Base 10, base 1000, what difference does it make? As long as he uses SCREEN 0!

Pete :D

See my latest release, Base 10 digits for uz dum idgits!
