Hi - it's me again.
Is there a way to represent floor function (round down) and ceiling function (round up) in OOo? Normally you use edged brackets "[f(x)]" without the upper horizontal line for floor functions and edged brackets without the lower horizontal line for ceiling functions.

Thanks. I used "search" but, the title had no hint on floor/ceiling functions so I did not find it. So the solution is:
Code:
lceil 2.5 rceil = 3, lfloor 2.5 rfloor = 2

It is missing in the view->selection box. so I could not figure it out by myself.

Oddly enough, it's in the online help. Look under "Math formula editor" > Formula Reference Tables

That little gem is also in the other thread, which is why I referred to it, rather than just copy the answer over here.

I guess my plan has backfired, now that we've both spent more time on this than if I had just answered your question directly Wink

I know there are some rough spots, but in general, the OOo online help is some of the best online help I've encountered. Unlike many commercial packages that do little more than copy the menus, or maybe give one-line explanations, the OOo help has a lot of useful information. My reflex initially was to ignore it, but now I try to remember to at least check there first.

The help also has a separate life in Issuezilla (component="documentation", subcomponent="Online help"), and an active volunteer effort working to improve it, so if you do find problems, please report them.

As you said it really is in the online help. I think the reason why I copuld not find it is that there is no picture to the code. So I overlooked it.

I ran into this myself and finally realized that the way the help is presented actually make it most difficult to use for the primary thing that it's useful for: finding symbols that are not in the menu.

So, I took my own advice and filed Issue 72777.
