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.

round() can take ints and negative numbers for places, which round to the left of the decimal. The return value is still a float, but a simple cast fixes that:
>>> int(round(5678,-1))
5680
>>> int(round(5678,-2))
5700
>>> int(round(5678,-3))
6000

You can use math.ceil() to round up, and then multiply by 10
Python 2
import math
def roundup(x):
return int(math.ceil(x / 10.0)) * 10
Python 3 (the only difference is you no longer need to cast the result as an int)
import math
def roundup(x):
return math.ceil(x / 10.0) * 10
To use just do
>>roundup(45)

r/processing on Reddit: Rounding number to nearest 10?
September 7, 2016 -
Hi, I'm wondering how I'd go about rounding any given integer to the nearest ten. (i.e, 11 into 10, 156 into 160, etc.)
EDIT: Got it, for anybody wondering the code I used was: x = floor(x)/10; x = x*10;
Top answer 1 of 5

the code I used was: x = floor(x)/10; x = x*10; Shouldn't it be x = floor(x/10)? floor(x) of an integer would just give you x back. Also that wouldn't round it.... You're dividing it by 10, flooring it, and then multiplying it by ten, so it only ever rounds down, never up. Ex: 17 --> 1.7 --> 1 --> 10

Not sure the exact code from my phone but you could do something like floor(n+5) but it only works correctly for positive numbers.
