ANGEL Issue Updates: December Release

We’re expecting a software release from ANGEL on Monday, December 15, 2008. The release includes two fixes that were requested by JCCC. As soon as the patch arrives, we’ll test and if possible install on production before the holiday break. Here are the details:

• Algorithmic Math Computation Error - In the algorithmic question type in Assessments, ANGEL is calculating natural logarithms incorrectly. As near as we can tell, ANGEL is rounding the argument before calculating the natural log. This error appears to be happening with all three versions of logarithms (log, ln, and log10) supplied by ANGEL.
  
  For instance, Angel is saying that the answer to the natural logarithm of 1.49 is 0. The correct answer should be 0.39878. However, the natural logarithm of 1 is 0, which fits the hypothesis that ANGEL is rounding the argument (1.49 in this case, rounded down to 1) before calculating the logarithm.
  
• LOR Folders: Can't Access Course Items When Linked From Inside Folder - When linking to a folder in a LOR, it seems to work okay until you try to view one of the items inside the folder, at which point you get an Access Denied error. Linking to a folder should work, as specified in the ANGEL documentation.
  
  Linking to the individual items in the LOR works, just not linking to the entire folder.
