Why not use the quizzing system variables, at least to 'show' the results? They have the proper formatting.

For user variables, you'll need to use JavaScript to format the result.

I wrote the script

(function () {

var PZ_result = '$$PZ_result$$'.split('.');

})();

gives an error message

You need to use the API for JS, something like this:

var num = window.cpAPIInterface.getVariableValue('myVar');

window.cpAPIInterface.setVariableValue('myVar', num.toFixed(2));
