# How to round a number to the nearest integer in python?

In JavaScript I often use math.round(), but what is its equivalent in python?

It's `round()` in python. Example:- print(round(5.8)) print(round(5.3))

[ Laur€nt ] , in python there is no such function. to get it done, we can use an f-string like this: val = 42.1 print(f'{val:.2f}') # for more details have a look at the python docs result is: 42.10

I would not suggest using the round() method to get the nearest integer, it is because the round() method uses banker's rounds, which can give an expected (for normal use) result. For example: round(2.5) # 2 round(2.5, 0) # 2.0 This post has info about that issue. To get the desired rounding, we can use the decimal module, and change the rounding method. If you are not comfortable with that, you can make your own method. To use the above example. def my_rounding(num): '''It only handles positive integer''' q, r = divmod(num, 1) if r >= 0.5: return int(q + 1) else: return (q) print(my_rounding(2.5)) # 3 print(my_rounding(2.4)) # 2 https://www.sololearn.com/discuss/3284453/?ref=app

***JUMP_LINK__&&__Python__&&__JUMP_LINK , do not post a new question in this existing discussion. create your own thread in the q&a section. to get help, it is better for you to start your own post, otherwise poeple will not get aware of you. also keep in mind that we need: > a clear task description with input / output sample > a link that points to your code try > a description what exactly your issue is, (if possible including an error message)

Also, can you help me with this? In JavaScript, to have the result fixed to x digits after the decimal point, we use the toFixed(x) function, what is the equivalent in python ?
