I just looked it up. So, if I use Interfaces.Fortran Reals and 
Double_Precision I think that would be just fine.

I have always thought that long_float and short_float where the same as 
Fortran's double and single precision. This is confusing.

So Ada has

Float,
long_float,
short_float,
Interfaces.Fortran.Reals
Interfaces.Fortran.Double_Precision
