How can I write a function in Python that rounds a number?

Question

How can I write a function in Python that rounds a number, in the usual fashion. Numbers less than .5 round down, and .5 and above rounds up.

3.4 -> 3

11.9 -> 12

5.5 -> 6

Answer 1

Use the Python function round(). If you want to do it yourself, add 0.5 and then truncate.
