While porting and revamping my set (uniqueness) functions to Mathcad Prime 10 from Mathcad 15, I felt the need for speed. Whilst I have set functions that will handle functions (to some degree), I wanted to use a uniqueness algorithm that relied on presorting an array. However, Mathcad's built-in sort function won't sort functions. After having a slight think about the problem, I wondered if I could use the format string function. I can, sort of, in some cases, but not in general.
Apart from possibly digging around in the worksheet API, does anybody know of a more reliable method of converting a function name to its equivalent string or how to sort on functions?
