Floats & Currency question

So i see when you do the checkplease.py if you divide the 84.97 by 4 people you get a number that couldn't be easily paid. Is there a way to round to that $21.24 and drop the extra .0025 in the amount_due within python?

There's an actual "round" function:

round(val + 0.005, 2)

The added half cent makes sure the value is always rounded up.

The 2nd argument is how much precision you want the rounding to produce. A "0"would give you whole numbers.
