error A2006: undefined symbol : FpuDiv

[sjums]

Good evening Masm forum!

So far I've managed to find an answer for everything i needed in here or on SO.

Now, I get these errors and i can't really see how to fix'em  :eek

I'm trying, in the nxtRnd proc, to convert this: http://www.codeproject.com/Articles/25172/Simple-Random-Number-Generation into assembly

I use fpu because I have to divide 1 by (32^2 + 2), which gives me a 0,00097 something

My two problems are:

• Where can i store a number as (32^2 + 2) aka 4294967298
• Why does i get an error when making saying: error A2006: undefined symbol : FpuDiv (same for FpuMul)

I've attached the code so you can see what I'm doing  :U

And please! Be gentle, I'm new  :boohoo:

On the FPU:

;    mov ecx, 2 ;4294967298 ;(2^32 + 2)...f*ck
.data
MyFatNumber dq 4294967298
.code
  fild MyFatNumber
    invoke FpuDiv,edx,0,addr m_r,SRC1_DIMM or SRC2_FPU

Should work now ;-)

ohh dear god how could i miss that semi colon  :red

the Visual Studio debugger says that MyFatNum is a __int64 with a value of 4 after the division (which should've been 0,000something)


EDIT:

I'm figuring it out :D

Super many thanks for the reply :)
