How do you round a float to an integer value?

Question

How do you round a float number value to an integer number value?
For example: 4.30 = 4; and 42.5 = 43
I want to know how to do this in code. Give a brief idea instead of the solution.

Answer 1

I have figured it out after a few methods. Gordon's idea was the best and it worked better.
With the built-inround function, there were afew errors as Gordon mentioned. Therefore this should (not entirely sure, thats why, should) be a flawless round function.

Partha Jagdale the easiest way is by using:
number = float(input())
print(round(number)
Default decimal place of round func is 0, you can manually set it by round(number, x) where x is the decimal places

Hope this helpful! Programming is fun! 😄

Partha Jagdale Actually it is not flawless, the built-in round function follows `Banker's rounding`, which is handling all 0.5 in a specific way to avoid having an over-large sum. Explicitly, it rounds up and rounds down alternately, so that the rounded result is always an even number.

Bearing in mind that the built-in round function uses banker's rounding, if you want to use Maths rounding (always round up), it is better to define the function yourself.

WenHao1223 Can you try this code snippet in code playground, and share yout result?

print(round(1.5))
print(round(0.5))

Answer 5

Thats why the "should" is there. ; )
So basically each method has its ups and downs, but it's best to customize the code for our needs.

Answer 6

def mathRound(num):
if.... :
return....
else :
return....

Answer 7

Use casting technique.
