Subject [jira] [Commented] (TAJO-339) Implement sin( x ) - returns the sine of x (x is in radians)
Date Fri, 29 Nov 2013 07:44:35 GMT

    [ https://issues.apache.org/jira/browse/TAJO-339?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13835234#comment-13835234

Hyunsik Choi commented on TAJO-339:
-----------------------------------

Only double type may be enough now. Tajo needs to support auto type casting mechanism for
expressions and UDF system. sin(x:int) function will be supported with auto type casting mechanism.

If you want to assign this issue to yourself, feel free to tell us.
