Jonathan Coveney updated PIG-2132:
----------------------------------
Release Note:
All I did was go through all of the Max and Min functions in Piggybank and add
if (first==null)
return second;
if (second==null)
return first;
Following conversation on the message board, the desired outputs are:
null,null -> null
1,null -> 1
null,1 -> 1
1,1 -> 1
This change gives that.
Status: Patch Available (was: Open)
This is my first patch, so I hope that I conformed to procedure properly. If I
should do anything differently, please let me know.
