You can put in a type name of any floating point type,
e.g. one that has "digits 36" in it's declaration.
The compiler you are using will tell you whether it can
support a floating point type with 36 digits.
If so, then Dmitry's generic can be instantiated with the type.

If you need to use results in another language (through a
binding), have a look at Interfaces.C; there are C_float and
related types. They should match FPT types in other languages
(that typically do not support programmer defined FPT types).
