Thanks for the quick response. From your description of the patch, it
sounds like you addressed the error that occurs using Gambit. But did
you also have a look at the odd rounding behavior I reported in my
first message?

earlier:

I get the same result with MIT Scheme. I must be missing something. Why do you consider it wrong? According to R7RS (and probably earlier versions of the standard),"round returns the closest integer to x, rounding to even when x is halfway between two integers."

Sorry, I wasn't clear. I was talking about this:

2> (format "~a & ~7,2F\\%\\\\\n" "Framingham Mass Muni Purpose Loan" 1.997554209949891)

"Framingham Mass Muni Purpose Loan & 2.10\\%\\\\\n"

Why does a ~7,2 formatting of something just under 2 result in 2.1? When, as you say,

3> (/ (round (* 1.997554209949891 100)) 100)
2.
