\noindent The function \texttt{quote32} has two purposes: it is meant
for pretty-printing of \textsc{us} treasury bond quotes; and it provides
a parser for prices quoted in 1/32 fractions.
\texttt{q32} is a short-hand for \texttt{quote32}.

If price is numeric, it is interpreted as a quote in
decimal notation and translated into a price quoted in
fractions of a point.
<<>>=
quote32(100 + 17.5/32)
@ 

If price is character, it is interpreted as a quote in
fractional notation.
<<>>=
q32("100'105") + 1/32
q32("100'10+") + 1/32
q32("100'10+") + 0.5/32
