This throws me.

Ah, yeah.. Not in love with the name of the function, which may go a little ways to explain what the purpose is (beyond, you know, some actual docs....).

For display in a template, I needed a quick way to format a dollar amount to two decimal places without rounding.

E.g.

123.4 -> 123.40
123.45 -> 123.45
123.456 -> 123.456
123.4567 -> 123.4567
123.45670 -> 123.4567

and so on.

Or three decimal places, which is why I added the decimal_places arg. We have some tracts of land that have fractional acres, but the majority are whole numbers. So I wanted to just show 123 if the acres were 123.000, but 123.456 if the acres were 123.456.

I don't think I've actually pushed that local change actually.

I need to clean it up a bit to clarify things, because even I'm confusing myself thinking through it right now.. 😅
