[LON-CAPA-users] math formatting

[Todd Ruskell]

Jay,

Try <m eval="on">\[1/ $a\]</m>.  The eval="on" tells the system to
escape the $a.  Depending on your situation, you may also want to
experiment with the &format command:

<m eval="on">\[1/ &format($a,'2e') \]</m>
<m eval="on">\[1/ &format($a,'3f') \]</m>
