Proper way to do string formatting

[rdbo]

I tried the following ways to format a float to have 2 decimal place precision, but neither worked:

{{ "%.2f" % price }}

Result: invalid operation: tried to use % operator on unsupported types string and number

{{ "%.2f"|format(price) }}

Result: unknown filter: filter format is unknown

Is it possible to format strings like this without creating a custom filter? If so, what is the proper way to do it?

Today a custom filter is the only thing you can do. I would love to have a formatting filter in minijinja-contrib but it's quite a bit of effort to create and I did not have the time yet. Happy to accept contributions.
