Description allaw 2005-02-10 17:08:11 UTC
I have been used StarOffice since the release of version 5.0. then moved to
OpenOffice. One of the things that did not change is the Math Editor. Although I
like the Command method of input, it is not enough in terms of lack of some
1. It lacks some symbols or operators and a problem of spacing if you try to
type them directly. Take this example and see the spacing:

y'''_{t+1} = x"*"_{t} + e_{t+1}

Notice the spacing for superscript {'''}. This is a symbol for the third
derivative.. The prime symbols are far from each other. The second issue the
location of the subscript {t or t+1}. These subscripts belong to the variables y
and x and therefore should be very close to these variables. Their location
should be aligned with or below the superscript.

2. The second feature would be a great enhancement is the ability to align two
equations to a character or "=". I am doing that manually. MS Equation 3.0
allows you to do that. Latex allows you to do that. Here is an example that
needs manual alignment:
y_{t+1}= a + b x_t + e_{t+1}
x_t = f x_{t-1} + c q_t + %eta_t

3. The third feature is to add "copy", "cut" "paste" functionality to the
right-hand button of the mouse.

I checked OpenOffice 1.9 m74. I found no change to the math editor which is
disappointing. I asked these features when I tested StarOffice 6.0. Two versions
later nothing has changed since, except for the math format and some cosmatic

Target set to OOo 2.0.1.
As agreed with MRU it may also be changed to Target set to OOo 2.0.2.
Comment 2 thomas.lange 2005-04-05 08:37:56 UTC
As fort the first issue:
See issue 43926.

As for the rest: It's a request for enhancement and thus I'll pass this one on.
Terget removed.
Comment 3 aviel 2005-04-27 14:42:59 UTC
See related discussion in OOo forum:

Also, what I miss the most is "search and replace" that includes formulas.
Comment 4 ajacoby 2005-06-13 18:40:01 UTC
Other requests...

An arcover command (like lineover) for describing arcs of a circle.

Shortcuts for common math symbols like degree and congruence.
Comment 5 carrus85 2005-09-01 00:54:29 UTC
Some additional requests:

Support for more operators (such as exclusive or (xor), therefore)
Aliases for common commands ( not should do same thing as neg, implies same
thing as toward, etc.)
Perhaps a docking panel that contains the symbols?
Ability to have function object inherit size/color settings from base document
in writer?
Ability to embed functions inside of cells in OOo Spreadsheet...
Comment 6 allaw 2007-03-04 22:12:21 UTC
It has been two years since this issue has been reported. I don't see any change
or any intent to change any thing to math editor, which really discourage any
one wants to write a document with advanced math.
Comment 7 lapsap7+ooo 2011-06-13 10:35:31 UTC
For the 2nd issue (alignment), it's in issue 5998.

Ugly workaround to have an arc over

(In reply to comment #4)
> An arcover command (like lineover) for describing arcs of a circle.

Yeah, it would be nice to have this command.  For the moment, I've only found an ugly workaround by using csup and "⌒", the Unicode character for arc (U+2312).  The attached image shows the following three examples: 

"A" csup{"⌒"}
"AB" csup{size 12 "⌒"}
"ABC" csup{size 16 "⌒"}

It's really ugly but I don't know how to move the arc down near to the letters or how to stretch the arc horizontally.

Currently there is the breve command.  So actually Math is almost there.  You just need to turn this thing 180° around and that's it!
Comment 9 lapsap7+ooo 2013-10-07 17:28:50 UTC
While waiting for the never-coming implementation :( I have come up with an alternative to using OOO Math:

* Use image instead of Math object *

Recommendation: save the text-based expressions as picture's "Description" to make it easier to change the expression in the future

Here are two suggestions:

1. Go to
 . Type in math expressions, use large font and resolution and download image
 . Scale down the image to have better resolution
 . Recommendation: backup Latex expression inside Description
 . For the arc, we can use either "\overarc {AB}" or "\stackrel \frown {AB}"

2. Use Wikipedia's math rendering engine
 . Edit any Wikipedia page (but DO NOT save it), or even better, use Sandbox at
 . Similarly, type in math expression using Wikipedia syntax, eg <math>\overset{\frown}{AB}</math>
 . See the preview and right-click on the image to save it
 . Check for the syntax
 . Contrary to the first suggestion, it's not possible to change resolution of Wikipedia rendered images
