Round integers to the nearest 10
python
Solution
Actually, you could still use the round function:
>>> print round(1123.456789, -1)
1120.0
This would round to the closest multiple of 10. To 100 would be -2 as the second argument and so forth.
Problem
I am trying to round integers in python. I looked at the built-in round() function but it seems that that rounds floats. My goal is to round integers to the closest multiple of 10. i.e.: 5-> 10, 4-> 0, 95->100, etc. 5 and higher should round up, 4 and lower should round down. This is the code I have that does this: ``` def round_int(x): last_dig = int(str(x)[-1]) if last_dig >= 5: x += 10 return (x/10) * 10 ``` Is this the best way to achieve what I want to achieve? Is there a built-in function that does this? Additionally, if this is the best way, is there anything wrong with the code that I missed in testing?
