Round up with negative ndigits

Question

I have the following below code, which works as :

num = 191360.789242721
round(num , -3)/1000
>>> 191.0

But how I can round UP and get 192.0 ?

Round up would be `math.ceil(num / 1000)` – Blownhither Ma May 14 '18 at 16:51 — Blownhither Ma, May 14 '18 at 16:51

You can use math.ceil() as a ready-made solution or do it manually with a reverse floor division:

num = 191360.789242721
num_ceil = -(-num // 1000)  # 192.0
