  • I assume that you read the [documentation for `round`](https://docs.python.org/3/library/functions.html#round). Which part of it do you have problems with? – Matthias Jun 18 '17 at 15:40

Life will be easier for you, as a programmer, if you use google. And I mean no offence. In this case, just query for python round.

In this particular case, if you want to round a float called BMD to two decimal places then you would use the following expression,

round(BMD,2)

You might also be interested in how to use formatting to achieve a similar result. First I deliberately set BMD to a value that has only two decimal places. I can print it as-is but I have no control. In the second case, I set BMD to a value for quite a few decimal places but this time I limit the number of output decimal places.

In my opinion, it's safer to use round and then use the first formatting option because the second option could stumble with a value such as 345.22 (which occupies more than four columns overall).

>>> BMD = 5.21
>>> print ('BMD is {}'.format(BMD))
BMD is 5.21
>>> BMD = 5.213333333333333
>>> print ('BMD is {:4.2f}'.format(BMD))
BMD is 5.21
