The documentation states, quote

175/200 = .875; .875 * 100 = 87.5 which is rounded up to 88

Using the example provided in the official documentation produces 88px.
However when dividing 5/2, it results in 2 instead of what I would expect
to be 3.

{{{
{% widthratio 5 2 1 as width %}
The width is: {{ width }} {# results in 2 instead of 3 #}
}}}

{{{

When using 7 instead of 5, the width results in the expected 4.

Comment:

`widthratio` uses built-in `round()` on floats so it's not really a bug,
see [https://docs.python.org/3/library/functions.html#round a note in
round()'s docs].
