6. Bugs

1. epc cannot handle variables with names that are too similar. It rejects any variable-assignments in which the new variable-name matches the beginning part of an existing variable-name, or vice-versa. (Note: if it doesn't reject a name, then there will be no problem in the calculation, so this is a limitation, rather than a bug.)

2. The default number of trials may be too large for slow computers, or too small for the accuracy of some applications.

3. Nobody seems to agree on what the notation '+-' means, but at least epc is consistent; to test it, try

   $x = 1 +- 0.1; calculate 2 * $x;

   and you should see the approximate result 2+-0.2, as expected no matter what you mean by +-. So, this isn't a bug, is it? :-)
