pitch~

Hi,
I want to use [pitch~] and I have two (simple) questions: Is there something like a round function e.g. when pitch finds the pitch value 71.9566 it is an C (72). I would like to have a function which make the int 71 from a value up to 71.499 and the int 72 from 71.5 to 72.499 etc..

And than I want the tuning of pitch~ 442 hz or better ajustable. I am aware of the ej.mtof but don't know how to use it inside pitch~

Thanks for assistance,
