Stop having math expressions show approximate value

So, I am creating an activity where I want students to give the exact value (in terms of pi) as well as an approximate value (rounded to 3 decimals). I was going to just have two separate math expression entries, but when students type the exact value into the math expression box, it automatically shows the approximate value (rounded to 4 decimals).

Is there any way to change a setting or put in a CL code so that the approximate value is not shown?

disableEvaluation: true

Thanks! I just figured that out based on another activity I had done.
Now I actually know what that command does (I thought it did something different, but put it in this other activity since the teacher helping me with it told me to…)
