   @beliefer can you document the new functions in the PR description?
   
   Basically can you list
   1. the function signature (name and argument type)
   2. Argument valid input range. Maybe some examples
   3. Not valid argument inputs. Maybe some examples.
   4. other special cases if any.
   ?
   There are usage comment for each expression. We can also copy documentation above into those comment.
