[Implemented] 64 Bit variable handling

It will be nice if in PB will exist 64 bit variables (QWORD - 8 byte), and maybe even 10 - byte variables.

This topic has been posted several times; 64, 80 and 128 bit variables for integers and/or real numbers are wanted, but for the moment you can use some user PB-lib for it, or build your own Structures

I didn't see any workaround about that, and even I didn't see that nasm suports QWORD. I would be greatfull if you can show me how to do that, if you know.

PB uses fasm now.
Nasm and fasm support, of course, QWORD (64bit), TWORD (80bit) and DQWORD (128bit), just because intel processors support it.

There are some user-lib which allow use of big numbers. I use bignum.dll by Rings.

Or you use either my F64 or my pbAPM (very, very large numbers

Library, both can be found on http://www.purearea.net

Huge work.

Having APM, why F64?

However, i've tried this and it hangs!

Code: Select all

gh.l=APM_New()

APM_Val(gh,"3.4345346563090984033467344")
APM_Add(gh,"0.0000000000000000000000001")

Debug APM_StrFixpt(gh)

Now, you can't add a string, it has to be another apm value.

As to the question with F64 vs APM. F64 is faster, APM more flexible.

Sorry, freedimension, i read help, but i did't see it

Code: Select all

gh.l=APM_New() 
gm.l=APM_New()
APM_Val(gh,"3.43453000010000465630909843456323452534536764545735634634264563434563456347033467344") 
APM_Val(gm,"0.00000000000000000000000000000000000000000000000000000000000000000000000000000000001")
APM_Add(gh,gm)

Debug APM_StrFixpt(gh)

I guess PB will never support so big numbers 8O
So your AMP library must be well keeped.

WoWWW, MisterDr, here you have a very accurate real and integer numbers:

Code: Select all

gh.l=APM_New() 
gm.l=APM_New() 
APM_SetPrecision(500)
APM_PI(gh) 

Debug APM_StrFixpt(gh)

Thanx man, Im now porting some applications from 3d state, and it's sucessfull until I received QWORD from 3dstate's Dll, and I stucked.
I tryed with structures but nothing. Received content form state's dll is not formated as I expected, because of values like 788.23267263772 and I canot just catch High or Low dword.
