The Proof General protocol does not understand pgreal, but happens to 
interpret a pgint value in a way that accepts floating point numbers as 
well -- the target language is Emacs LISP where everything is untyped 

Since you are hooked on that accidental protocol as well, you should 
imitate the LISP code.
