Round up to the next multiple of 5

Given an integer as input, can you round it to the next (meaning, "higher") multiple of 5?

Examples:

input:    output:
0    ->   0
2    ->   5
3    ->   5
12   ->   15
21   ->   25
30   ->   30
-2   ->   0
-5   ->   -5
etc.

Input may be any positive or negative integer (including 0).

You can assume that all inputs are valid integers.

 

 

Solution:

1. Divide n by 5 and round up.
2. Multiply the rounded value by 5.

 

def round_to_next5(n):
    import math
    return math.ceil(n/5)*5

 

 

In addition to rounding up, the remainder can be used to obtain a value.

def round_to_next5(n):
    return n + (5 - n) % 5
