API Question: Programatically find how many decimal places in currency

I am doing a calculation based on the price of an item $bonus = $original_price / $some_value and sometimes it rounds odd like $1.0563454

I could simply round it, but I realized that digital currencies have more than 2 decimal places so rounding to $1.06 may not always be appropriate.

And sometimes users set the currency to round to whole number as well…

So is there a way to determine the WooCommerce current decimal setting?

I’d like avoid having to put it as an option a second time in my plugin.

Thanks!
