So I wrote a function: def float2n_decimals(floatt, n): """ Given a float (floatt), return floatt to n decimal places. E.g., with n = 2, 81.34567 -> 81.35 """ return ("%%.%sf" % n) % floatt which works fine, but a question remains: n is an integer. Why the 's' in '%sf'? (Also, please suggest a better name for this function.) See this latest revision at <http://tutoree7.pastebin.com/K9ikqNFC>.
