Upgrade to latest version of Mneme (Test Center), and patch as appropriate. We're currently at 2.1.9, and the latest version as of this date is 2.1.18:
1. Note that tiny mce is no longer needed for Mneme… but if any content was authored in the past with Mneme using tiny and the emoticons, then the URL to these images got stored in the content as a reference to files in the tiny web app. Because of this, we left our tiny web app in our deployment.
2. *MN-1188: Messy values heading to Gradebook - FIXED
When question values use decimals, the values being sent to the gradebook are messy - instead of a nice clean "0.3" or "0.2" we are getting "0.300000011920929" and "0.200000002980232 in GB's database records. (Mneme's database is clean). This is leading to occasional incorrect rounding to whatever decimal precision GB is using, for example (as seen at U of M and reported by Diana Perpich), a score of XXXX.3 is sometimes reported as XXXX.29.
The problem is that Mneme's float precision does not match GB's double precision, and the float to double code is picking up noise. We can do a more careful conversion to avoid the noise.
