NumberUtil::round() public WC 1.0
Round a number using the built-in round function, but unless the value to round is numeric (a number or a string that can be parsed as a number), apply 'floatval' first to it (so it will convert it to 0 in most cases).
This is needed because in PHP 7 applying round to a non-numeric value returns 0, but in PHP 8 it throws an error. Specifically, in WooCommerce we have a few places where round('') is often executed.
