Python - round up to the nearest ten

If I get the number 46 and I want to round up to the nearest ten. How do can I do this in python?

46 goes to 50.

Solution

  • 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)
50
