Knut Anders Hatlen commented on DERBY-3874:
-------------------------------------------
I think the patch looks good. +1 to commit. (rrefjdbc88908.html and
rrefsqlj55788.html in the zip file didn't mention atan2, but they looked OK
when I built the docs myself.)
To answer some of your questions:
> (However, there seem to be no implementations of POWER, ROUND, or TRUNCATE,
> for whatever reason.)
Before DERBY-3063, we had none of the 2-arg functions. ATAN2 was added in that
issue, and I thought the plan was to add the others as well, but the issue
appears to have been marked as resolved. It should be easy to add the other
functions now that we have the mechanism in place, so if there isn't an issue
for it yet, we should file one.
> I'm guessing we should put the four supported ones (cot, radians, rand, sign)

Yes, that makes sense.
> Derby's support for the other functions in this appendix (string, time and
> date, system, conversion) is much spottier, apparently. (...)
> Would it be legitimate to add these to the "JDBC escape syntax for fn
> keyword" topic?
I can't see why it shouldn't be legitimate. And as you said, we already
document some of the string and time functions there.
> Document numeric function ATAN2(float1,float2)
