How to use the readline-sync.questionFloat function in readline-sync

new NativeExpression((context) => {
                process.stdin.pause();

                let input = readline.questionFloat('');

                console.log();

                let value = Obj.create(context, Types.Double);

                value.set('value', input);

                process.stdin.resume();

                return value;
            })));
    }
