Hello everybody!

I'm trying to do some calculations in assembly and return the results to 
djgpp application..
I've no trouble returning integers (32 bits) in eax, but with floating I 
get -NaN (not a number)

global _atest

section .data
    p dd 0.2

section .text
     mov eax, [p]

and receiving as float (I've tryed with double too)
extern "C" float atest();
void main() { float f = atest();  cout << f << endl; }

and I get -NaN

Any idea?

Thanks in advance!
