Subject [jira] Commented: (DERBY-3874) Document numeric function ATAN2(float1,float2)
Date Mon, 22 Sep 2008 21:54:44 GMT

    [ https://issues.apache.org/jira/browse/DERBY-3874?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12633521#action_12633521
] 

Kristian Waagan commented on DERBY-3874:
----------------------------------------

You can supply NaN and Infinity as arguments by using a prepared statement from Java. However,
this results in the exception with SQL state 22003 (as per the code snippet above).
I'm sure there are several wrinkles in this area. To collect some information, does anyone
know the answer to the following questions?
 - Should returning positive zero instead of negative zero be considered a bug?
 - Are we able to separate between the two in Derby today?
 - Why are we not allowing NaN and Infinity?
