Hi,

I'm using vc++ 2008 express.

I cant get a correct float result.

After searching for solutions I have this:

+ Code Snippet

#include "stdafx.h" 
#include "t1.h"       //name of dll
#include "windef.h"
#define DLLEXPORT extern "C" __declspec(dllexport)
//    division function
 DLLEXPORT DWORD Div ( float A, float B )
{
float result;
result=A/B;
return *(DWORD*) &result;
}

It compiles fine and the string tables are in there okay.

DBP accepts it as function like this:

+ Code Snippet

a#=10.0
b#=5.0
print div(a#,b#)

but the result equals 1073741824.

NOTE: All the integer function I've done work fine.

Can someone please help with the floats?

regards,
miki.

Sorry, It's C++. Not ASP.

sorted... changed my LLL to FFF

in the end

Hah, I had the same problem a little earlier today - I had written D instead of F by mistake.
