style.set_precision(0) displays spurious .0

The expected display format would be as in [2]:

looks a bit buggy, want to do a PR?

Okay, I guess the Jinja2 docs recommend to do this by changing this to something like this:

{% if c.value is number %}
    {% if precision %}
        {{c.value|round(precision)}}
     {% else %}
         {{c.value|round|int}}
     {% endif %}
{% else %}

Okay to put another branch like this into the inner loop?

I think that is ok, the rendering time is not usually an issue (unless you are rendering millions of lines, which itself is an issue anyhow).

{{c.value|round|int}} fails with nan and inf, so the submitted PR uses percent-formatting

[TomAugspurger]

Sorry, I didn't see this until now. I've got branch that is changing how the display formatting works, which is going to conflict with your PR in #12137. I believe I've fixed this bug in the change (here if you want to take a look at the relevant bit). I'm going to clean that up and submit sometime this week.

It boils down to using formatting like

In [4]: '{:0g}'.format(100.0)
Out[4]: '100'

when your precision is 0

No problem, more control over formatting is nice, stepping back.

Does this unify rendering of NaNs (IIRC df.style displays nan and normal html rendering NaN)?
