Is the DLL and the calling programm compiled with the same Compiler. I had a 
similar problem some time ago, when calling a procedure in a DLL that was 
compiled with Zortech C++ from a programm compiled with Borland C++. The return 
of float and double values is incompatible between Borland, Mircosoft and 
Zortech. If my memory is right, Borland uses the floating point registers (if 
no floating point hardware is present, Borland uses an emulator, so there are 
always floating point registers), Micorosoft uses a static memory location and 
Zortech uses CPU registers.

Using floating point return values is unportable between different compilers!
