Hi Jim,

I call a c++ library that return some values in c++ double format, using the ndFpCall, they are converted to Xbase++ numbers.

Regards,
Edgar

DllCall() returning the value from the EAX register but returning double 
are storing the result in the FPU stack, so DllCall() just returning 
something random on those cases
