I have not used the decimal module (until tonight). I just now played around with it some, but cannot get it to do an exact conversion of the number under discussion to a string using str(). I notice that the module has the methods to_eng_string() and to_sci_string(), but I see no substitute for str() listed. Surely there is some way to use the decimal module to get the desired conversion to a string? I have to retire for the evening and will try to figure this out tomorrow.
