# Taking Math Input an rounding it to 2 decimal places to use in CL text

I am trying to give students feedback in an activity through CL text. Some of the questions require that students input their answers as fractions, but I want to limit my feedback ouput to just 4 decimal places. How can I code this?

Here is an example of my code:

content: “{question} {feedback}” (note: missing strings are really there in the code)

question = "A recent survey of American adults found that 638 of 840 have a favorable opinion of the current presidential administration. Develop a confidence interval for the actual proportion of American adults that have a favorable opinion of the administration.

What is the sample proportion \hat{p}?"

feedback =
when Input21.submitted and Input21.numericValue< answerhigh and Input21.numericValue> answerlow “\n\n\n✅Good job. ${Input21.numericValue} is correct.” when Input21.submitted “\n\n\n❌ Nope. Remember, we are now looking for a sample proportion. This is simply the number of adults who approve of the president divided by the number that were asked.” otherwise “” I want the output for the correct answer “\n\n\n✅Good job.${Input21.numericValue} is correct.” to be limited to a certain number of decimal places (in this case 3). How can I make this happen?

n1 = numericValue(\round(\pi,2))
n2 = numericValue(\round(.0123456,4))
n3 = numericValue(\round(${Input21.numericValue},4)) content: "this is${n1}   \nand this is another number: ${n2} \nand for 638/840:${n3}"
