There are a few more corner cases, such as numbers that print
with scientific notation, but it's not too late to collect your examples
plus some more to make a test suite and fix any remaining bugs.

You may also be interested in SRFI 159 <https://srfi.schemers.org/srfi-159/>,
where your initial example
becomes:

  (show #f "Framingham Mass Muni Purpose Loan & "
    (with ((precision 2)) .997554209949891) "\\%\\\\\n")

This code is fairly mature, based on the portable fmt
<http://synthcode.com/scheme/fmt/> library which
has been tested on a variety of implementations.

At any rate, feedback on the SRFI would be appreciated :)
