python round to nearest multiple of 3 code example

Example 1: python round down to nearest multiple of number

# Basic syntax:
import math
math.floor(larger_number / multiple) * multiple

# Example usage:
# Say you want to get the nearest multiple of 5 less than 29
import math
math.floor(29 / 5) * 5
--> 25

# Note, you can also do this with div if you don't want to import math
29 // 5 * 5

# Note, to get the nearest multiple of 5 greater than 29 run:
math.ceil(29 / 5) * 5
--> 30

Example 2: round to nearest multiple of 5 python

def rof(x):   '''round up to multiple of 5'''
    if x%5==4:
        x+=1
    elif x%5==3:
        x+=2
    print(x)
