Description tdunning 2005-01-28 05:34:44 UTC
Slash should scale with the arguments on either side.  Thus:

{binom x y} / {binom a b} 

Shouldn't have the worthless little slash, but rather should have a tall one. 
Even if this isn't the default behavior, there should be a documented way to do

MRU->TL: can this useful thing be solved for predecessor of OO 2.0?
Comment 2 thomas.lange 2005-01-28 08:30:27 UTC
It is already there the name is "wideslash" and it can also be seen in the list
of functions/operator of the context menu for the edit window.
Comment 3 thomas.lange 2005-01-28 08:30:47 UTC
Set to invalid.
Comment 4 michael.ruess 2005-01-28 08:40:57 UTC
I should have known thisby myself. Already exists...
Comment 5 tdunning 2005-02-23 21:16:45 UTC
Actually, I tried wideslash recently and the results were unusable.

THe problem is that what is needed is a scalable slash that is the height of the
taller of either of its arguments just the way that scalable brackets work.  It
should not reposition either of the arguments.

What wideslash does is set the left argument a little higher and the right
argument a little lower and put a slash between the two.  The result is
particularly ugly and not at all what is needed.  What is needed is something
much more like what mline does.

I will try to attach a picture of what I mean.

reassigned to requirements.
Comment 8 Matthias Basler 2005-02-28 17:01:52 UTC
Yes, wideslash is not what is needed.

Please check issue 43577 (different operator, same topic. Duplicates?). 

I believe this issue is more general and applies to several operations and
symbols that need a scaling equal to the brackets and such.
So I would suggest to have all (or many) operators and integrals in two
versions, one unscaled and one scalable ... just as it is with the brackets and
e.g. "sum" and "largesum", "/" and "large/", "divides" and "largedivides" ...
Alternatively the largeXXX operators/symbols could be static in size, but simply
Comment 9 tdunning 2005-02-28 20:15:21 UTC
I don't think that summations and integrals should work quite like this. 
Probably the best thing to do on that account is to look at what TeX does since
that is almost by definition acceptable.

It is clear that there are a number of symbols that need this treatment.  Issue
43577 is definitely another instance of the problem.  Thus, divides and slash
need it, but plus and times don't.  Again, TeX should be the reference.

I just installed OO 3 on my mac to test this.

Unfortunately, the equation facility is completely unusable due to some sort of
odd font bug.  All brackets, slashes and so on are replaced by goofy symbols.

OO is uninstalled.  Again.

Maybe someday.  I keep hoping.
Comment 12 Matthias Basler 2008-05-16 17:00:38 UTC
Retested with OOo2.4.0 on WinXP SP2.
Issue remains unchanged. Sad issues like this aren't addressed within three years.
