Here's a solution that even those on a government budget can afford:

Instantiate Text_IO.Float_IO.  Use the string-to-float version of Get to
write your own Value function (or use Get directly if that solves your
problem).  Use the float-to-string version of Put write your own Image
function (or use Put directly).

Your compiler maker has already done the hard work by providing these
procedures.
