I have used this code in the past when comparing input answers to what I want:

```auto
\\operatorname{round}\\left(${expectedValue},2\\right)

```

and that works, but when it comes to showing a rounded decimal in the content doesnt round. What can I use to round a calculated number and then show it in the displayed content?

Make a variable with that code, and display that should work. The only time I don’t think it works is if there’s a trailing zero.

</div>

```auto
t=results.script.total
tp=results.script.totalpercent
tpr="\\operatorname{round}\\left(${tp},2\\right)"

content: when numericValue("${t}") = 100 "FANTASTIC ${studentName.content}! You got all ${tp}!! See the details below:

👈🏿 Tell us how you're doing

"

otherwise "You got `${tpr}` correct out of 100%. Try to go back and fix your work. You got this ${studentName.content}! 

👈🏿 Tell us how you're doing
"

```

You’re just displaying the latex. Try using numericValue for tpr.

There’s a % character in tp that might be the problem.
