I tried to output the calculation result. The ideal result would be like: "ps = k tp + b "according to the "IF processing". The "tp" here actually relates to the time, but right now I just want the result to be like the form I mentioned above. In other word, I think and hope the "tp" is just a symbol in my ideal output result.

So I tried to set it as a  "key word" or "constant" by setting the labels but found nothing helpful. Can any solution help me with this? Many thanks advanced !

If you expect a symbolic result (as tp is an undefined variable) you have to use symbolic evaluation and not numeric (the normal equal sign).

Is it this you are looking for?  No need the re-label tp as Keyword or anything else.

Number of decimals is per default 20, You can limit this number using the "float" keyword. But keep in mind that doing so also affect the precision of the calculation, not just the display of the result.

Hi !

I mean, this is where the  problem occurs. I try to set the "tp" as  symbol, but it keeps telling me that the "tp" is undefined and to recheck the lable that I set.

I change the definition btw, two variables are needed in this function I defined actually.

I do a little modification. Instead of outputting the ideal equation form that I need, I try to calculate the coefficients "k" and "b". But there is a new problem occurs indicated that "This value must be a function".😥
