Make Nintex Workflow and Nintex Forms formulas Consistent

I came to the conclusion that the function fn-DateDiffMinutes (Nintex Workflow) and DateDiffMinutes (Nintex Forms) produced different results. Nintex Workflow offered a pure result of a positive and negative number, and that Nintex Forms manipulated the result by converting it to an Absolute value.

I would like to make a few suggestions for your consideration going forward.
1.) Make them consistent in the pure sense where the result is positive or negative. Your documentation on the formula window when using the inline function versus the runtime function provide the exact same formula with nothing that indicated a different expected result. I looked in your documentation for both Workflow and Forms and scoured the forums too, there was nothing that provided any indication that the results would not be the same.
2.) Provide a more precise description of your formula and how they work to the end users, for not all of them are programmers and there is key info that a Business Analyst (non-developer) would need in order to have less problems. I have on multiple occasions struggled with your documentation, it is often vague when the end user is trying to decide how to use a feature to best fit their need, and wrong interpretations kill end users in trying to get our workflows out the door faster to help our teams.
For example
• fn-DateDiffMinutes(Date1, Date2)
• This takes Date1 – Date2 = result in +/- Minutes
3.) Since you have a function that allows the end user to convert the result to an Absolute value.
