Re: [LON-CAPA-users] Tolerances with Hints
Carl, Thanks for looking into that. Stuart actually tacked me on to the bug report. The printing of the tolerance was not my main concern. The use of the variable was so that if anyone overrode the tolerance externally (which it turns out can’t be done for the hint), then it would display properly. I had a chunk of code in the script that I did not copy into the note which loaded the tolerance variable using one of the loncapa functions.

Re: [LON-CAPA-users] Tolerances with Hints
I've done no testing on this but am wondering -- could the responseparams for the problem occur just before the closing or tag so that those are the values in force and would the other tolerance statements then still work as intended for their hints?

Re: [LON-CAPA-users] Tolerances with Hints
Hi Mark, It looks like you are wanting to display the tolerance in the hint? This can be done if you set the tolerance as a variable in the script. In the test environment this works OK. I have not tried to include it in a course. This problem provides hints if the answer is wrong but within 100% or 500%. Note that if the answer is within 100%, then both hints display because anything within 100% is also within 500%. msu/lira/loncapa examples/conditional hints.problem Code included here for quick reference: #Enter the computations here $a=&random(1,10,0.5); $b=&random(1,10,0.5); $c=$a+$b; $Tolerance = "10%" What is $a + $b? Your answer is within +- 100%. Required tolerance $Tolerance. Your answer is within +- 500%. Required tolerance $Tolerance. Your answer is off by more than +- 500%. Required tolerance $Tolerance. -Original Message- From: lon-capa-users-boun...@mail.lon-capa.org [mailto:lon-capa-users-boun...@mail.lon-capa.org] On Behalf Of Lucas, Mark Sent: Friday, February 16, 2018 10:43 AM To: lon-capa-users@mail.lon-capa.org Subject: [LON-CAPA-users] Tolerances with Hints Hi, I am looking to include a hint in a problem that occurs if a response is inside a wider tolerance (5%) but not within the requested tolerance (1%).
