If you want an unconstrained, 32-bit, signed integer type, something from 
Interfaces (such as Integer_32) is usually the way to go.

Why hope? If you need a 32-bit floating-point type, again something from 
Interfaces might be in order, or declare an appropriate type for your application:

type Real is digits 6 [range Low .. High];
for Real'Size use 32;

In any case, the size of Float should be documented for your compiler.

This shouldn't compile, as An_Integer has a different type than 
An_Unknown_Integer; you need a type conversion.

What is the point of Unknown_Integer_Type and An_Unknown_Integer? What's wrong with

A_Float := Float (An_Integer);

?
