Hi All, I dont think, we should think about the Java API when you are programming in Javascript. In JavaScript you have 4 premitive types (literals)
1. null 2. boolean 3. numaric 4. string And you have Objects as well for these with more operations associated see [1] so if you want to do numerical operations you have to cast your string to a Number and work on it. and thats it, an example is found at [2]. We cannot go on, providing operations such as *getParameterAsDouble* whenever we need some value to be casted, that's not Jaggery is for and thats not how you work with javascript.
