Gilles edited comment on MATH-1047 at 10/30/13 10:08 PM:
---------------------------------------------------------
Method "pow(long,int)" modified in revision 1537324 (using
"mulAndCheck(long,long)").
If a more efficient version is needed (possibly without safety check), it will
need to be reimplemented with another name, and documentation that clearly
indicates the purpose and caveat.
