[jira] [Updated] (PIG-2881) Add SUBTRACT eval function

["Joel Costigliola (JIRA)" <ji...@apache.org>]

     [ https://issues.apache.org/jira/browse/PIG-2881?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Joel Costigliola updated PIG-2881:
----------------------------------

    Attachment: SubtractTest.java
                Subtract.java

The tests relies on fest assert https://github.com/alexruiz/fest-assert-2.x but can easily be rewritten with Hamcrest I guess.
