I'd like to be able to convert a float to a string representation in which the number is rounded to a specified number of digits. If num2str is a hypothetical function that does this, then num2str(pi,3) would be '3.142' (not '3.141'). I've been told that there is no such function in Python. I tried to write this myself, but wasn't successful. Any suggestions will be appreciated.
