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
