Exactly my problem. Multiplying and using ceil might cause inaccuracy. Is it possible to round to the nearest floating point value, but rounding up. Something like `round`, but which always rounds up or rounds down. -- You received this message because you are subscribed to the Google Groups "sympy" group.
