Function to find the data type of a constant?

Question

Is there a function which can give the data type of a constant? The function "getcontentdetailsbyuuid" doesn't provide that information. 
 
 Use Case: 
 I want to build a UI for the business users to manage few constants. The UI should dynamically display the type of field based on the data type of the constant. example: Display date field for a constant with "date" as the data type

Will this work for you? fn!typeName(fn!typeOf(cons!YOUR_CONSTANT))

That was exactly what I was looking for. Thank you so much

Never mind, I answered my own question. I can just get the fn!typeOf(fv!item) where fv!item is the VALUE of the constant.
