Hi six_L, :thumbsup:

QuoteYou should blame me, not him.
I cannot and do not blame anyone directly, neither you nor jj.
I only expressed my opinion about the algorithm and the code of the program.
I wonder why jj is interrupting OUR conversation and acting in such a nervous manner.

QuoteI hope the competition continues.
After these insults from jj, I lost the interest, sorry! :sad:

The latest version. I had to tweak the code from our genius a little bit because a) it crashed and b) it overwrote the table, but now it works :thumbsup:

And indeed, Lingo's code is faster than mine :thumbsup:  :thumbsup:  :thumbsup:

I feel honoured that he used almost all my tricks :cool:

There are tiny little problems here and there, but hey, it's fast :thumbsup:

Thanks, LiaoMi :thup:

Your cpu beats mine by almost a factor three. That is a fine machine - I could become a bit envious :mrgreen:

I attach sources and executables for both 64- and 32-bit versions. Note it's the same source ("dual assembly"), there is just one option OPT_64 n on top, with n=0 or 1. My MbDw2Str has only two tiny conditionals on entry:
    if @64
        mov rax, rcx        ; xwValue
    else
        mov eax, xwValue
    endif
...
    if @64
        mov rcx, 051EB851EB851EB85h
    else
        mov ecx, 051EB851Fh
    endif

CRT sprintf requires a different format specifier:
    mov rcx, number
    if @64
        jinvoke sprintf, rdi, Chr$("%lld"), rcx
    else
        jinvoke sprintf, rdi, Chr$("%d"), rcx
    endif

The Roberts and Lingo versions cannot be converted to 32-bit because of their register usage. Latest timings:

Hi,Lingo

QuoteAfter these insults from jj, I lost the interest, sorry! :sad:
This is a scene that most of our members do not want to see. I respect your choice. It's you who exhibited us the power of assembly language and the dazzling skills.

jj2007 not only argued with you, but also with many members. such as hutch--/aw27/nidud/_japheth. Some outstanding members had left forever because of arguing. Arguing is his inherent attribute. Human beings need the biological diversity. i guess our forum also needs member diversity. you may ignore him.

Say you, Say me, Say the codes together for ever.

Stop this nonsense, dear. Yes, I argued with some of them, but it was always civilised. With Hutch, I had a very good relationship.

Lingo comes here out of the blue, never supplied a valid email address to our administrators, wants to take over the forum, posts crappy code, most of which (badly) copied from mine, and then has the chuzpe to call me a thief.

This is all documented in Bravo, Lingo!

I have no problem with Lingo using my code, although just using other registers to hide that sort of "reuse" is a bit fishy imho. I do have a problem, though, if he calls me a thief.

If I were the moderator, I would have kicked him out a long time ago.

Many of us hoped, that this site's old style vanish, but old dogs are, what they are.
I am only here, as i use Pelle's C and i need to know something about assembly, when i try to hunt bugs.
Hopefully this site users still have an open mind for programming.
May the source be with you

jj2007

I've added the fast algo to the MasmBasic library of 12 April 2024, in two flavours:

a) as Str$(number):
  Print Str$("Rect left/top/right/bottom=%i", [esi.RECT.left]), "/", Str$(MyRC.top), "/", Str$(MyRC.right), "/", Str$([esi.RECT.bottom])
Flexibel, and a tick faster than the Masm32 SDK str$().

b) invoke MbDw2Str, number: ultrafast but no concatenation as in a).

stoo23

I'll try this Again

Can you Please Read and Respond to the PM's I have sent.
Thanking you in advance,
