random number generator

[fusspot]

Is it possible to implement random number generation in assembler language?
If yes, how do i do that?

hi

here is a algo from firewoks project

random PROC base:DWORD        ; Park Miller random number algorithm
   mov eax, seed            ; from M32lib/nrand.asm
   xor edx, edx
   mov ecx, 127773
   div ecx
   mov ecx, eax
   mov eax, 16807
   mul edx
   mov edx, ecx
   mov ecx, eax
   mov eax, 2836
   mul edx
   sub ecx, eax
   xor edx, edx
   mov eax, ecx
   mov seed, ecx
   div base
   mov eax, edx
   ret
random ENDP

masmlib already contains a random number generator (nrandom)

[0x58]

and in case of generating 0.F --> 0123456789ABCDEF  ::)

 i wrote an asm version of the well512 random number generator(just google it).

theres a seperate asm file (well512.asm) that you can assemble and add to your own library if you want and a small example of its usage

last week - everyone was writing one    :P
look in the laboratory and workshop
