Missing formatNumber function in Mx runtime client

One of our widgets are breaking with the upgrade of Mendix 5.12 to 5.15.1 due to a missing function called formatNumber. Any suggestions on what to use instead and why was it removed?

You will have to use the formatValue, which is the same functionality but you have to call it in a different way. I had the same problem with the currency viewer widget, and used this function as documented at https://apidocs.mendix.com/5/client/mx.parser.html. It will look something like:

mx.parser.formatValue(3000, "currency", { places: 2, groups: true });
