No support for string() function #34
Description
The DMN specification includes a string() function to allow conversion from other data types (e.g. numbers)
When I try to evaluate string(1.1) as a FEEL expression I get
TypeError: Cannot read properties of undefined (reading 'fn') at processUserDefinedFunction (/home/david/x-rules/node_modules/js-feel/dist/feel-ast-parser.js:358:27) at processFnMeta (/home/david/x-rules/node_modules/js-feel/dist/feel-ast-parser.js:397:16)
Implying the function is not available as a built-in so it looks for it as a user-defined function.
Please can someone implement this?
