Writing the UDF was simple enough. How do I contribute the code

Please open a new jira (https://issues.apache.org/jira/secure/ 
CreateIssue!default.jspa) and attach your patch there... thanks!

PS: You will need a jira a/c to create a new jira.

Another question - I often find that the command 'illustrate' runs  
into more
heap space issues than a brute-force dump command. Isn't that  
contrary to
the goal of the Illustrate command - that it should pick a smaller  
data-set,
use lesser memory/cpu and finish faster?

 Sorry I'm stupid. FLOOR, CEIL are not aggregate. You have to  
write a UDF.


And if you do write one, please contribute it back to Pig! *smile*

I need to use the equivalents of SQL functions FLOOR, CEIL etc

And I'm looking for a list of complete PIG supported functions.

Is there any such documentation? Else, does anyone know if these
functions
are supported?
