How can you make python round numbers to the nearest 5:
Example:
3 => 0
8 => 10
23.2 => 20
36 => 35
51.5 => 50
I'm not sure *any* rounding system will give those results.
Round towards zero.
8 => 10 ?
One can round down with
def round_down_to_n(x, ROUNDER = 5):
return (x // ROUNDER) * ROUNDER
but 8=>10 still fails to pass because 3 rounded down and 3+5
rounds up.
So I call bogus data, or fall back to Miles' bogoround() function :)
