I have a meta box where a 'Case Result' CPT can be assigned a monetary value (e.g. $60 Million). I need to convert this into a decimal number for use as the `meta_key` in `WP_Query`.

I understand how to do the reverse (https://www.php.net/manual/en/function.number-format.php#89888), but want to know if there's a reasonable approach to taking a '$60 Million' string and converting it to '60000000'.

My current query is below, which is re-run across multiple 'Attorney' pages (hence the `$attorney_name` for `terms`) to show the only cases they were responsible for. I'd like to order these posts by their monetary value in descending order, but I'm aware the current config (`meta_type` etc) won't work with the value in it's current string state. Any advice would be massively appreciated.

```php
// Configure query
$query = new WP_Query( array(
    'posts_per_page' => -1,
    'post_type' => 'case-result',
    'tax_query' => array(
        array (
            // Filter CPT's to display by taxonomy
            'field' => 'name',
            'taxonomy' => 'case-result-attorney',
            'terms' => $case_result_attorney,
            // Sort CPT's by meta
            'meta_key' => 'case_claim_value',
            'meta_type' => 'NUMERIC',
            'order' => 'DESC',
            'orderby' => 'meta_value_num',
        )
    ),
) );
```
