How to string format a float to the 10s or 100s place?

Question

How do I string format, either % or .format(), a float to round and display to the 10s or 100s place?

Like 4552.33 to 4550 to 10s place or 4600 to 100s?

Can anyone dupe hammer this question with the link @roganjosh mentioned — Moinuddin Quadri, Feb 14 '17 at 17:42
@stephen all you need is `round(4552.33, -2)` and `round(4552.33, -1)` — Moinuddin Quadri, Feb 14 '17 at 17:45

Use the built-in function round,

>>> import math
>>> f = 4552.33
>>> int(round(f, -int(math.log10(10))))
4550
>>> int(round(f, -int(math.log10(100))))
4600
