Typeset/format numbers preserving trailing zeros
typeset_numbers(eq.char, output.type)A character string.
exponential number notation to typeset equivalent: Protecting trailing zeros in negative numbers is more involved than I would like. Not only we need to enclose numbers in quotations marks but we also need to replace dashes with the minus character. I am not sure we can do the replacement portably, but that recent R supports UTF gives some hope.
