Re: [libreoffice-users] Fractions in Maths

Hi! I think an interesting reason may justify the enhancement request. 


It is a matter of speed. For me, I need to use the keyboard very often. Typing 
Alt+I+O+F {2a over 3} (Esc) (Esc) (17 keys) is slower. Typing 2a/3 (space) (5 
keys) is faster.

 
(17-5)/17*100=70.59%

That is about 70 per cent of reduction in the number of keys I need to type 
(not using the mouse)! Amazing!

Regards,
C. H. D.

I am likely late to this thread, but why won't using
sqrt{4a^2 over 9} = +- {2a over 3}
as an LO "formula" work for you, or  using
\sqrt{\frac{4a^2}{9}}=\pm\frac{2a}{3}
in TexMath

While it would be grand to be able to simply have LO parse TeX (or your
math notation of preference), the two options above seem reasonable
compromises

[libreoffice-users] Fractions in Maths

[C. H. D.]

Hello, LibreOffice Developers and Supporters!

I need to handle some fractions in Maths in LibreOffice Writer. The fractions 
look like 1/2 or 10/40. I would like to make them look like:
　1
　－
　2
(no superscript and no subscript)

There are some possible ways to do this. A _proper_ way is: 
Insert -> Object -> Formula -> {} over {} 

My imagination is like:
Autocorrect the text as object. When typing 5/6 (space), I get
　5
　－
　6
which is an object.
(Ctrl + Z would return 5/6 (space))

My second imagination is like: Using Find & Replace to replace 7/8 as 
　7
　－
　8
I could get the object option in the Find & Replace dialog. 
Find: */*
Replace: (format as object)
　*
　－
　*
This could convert all the "horizontal" styles into the "vertical" styles.

My third imagination is like:
In LibreOffice Calc and in a formula in LibreOffice Writer,
I could have =7/8+1/8.
I could also have
　７　１
＝－ +－
　８　８
(These are objects.)
where LibreOffice could perform the calculation and give me the result in 
fraction.

This post below really led me to think that typing fractions could be a part of 
the fundamental work a word processor should be able to do easily:

Formatting Text as a Fraction (on 20 May, 2009)
http://forum.openoffice.org/en/forum/viewtopic.php?f=11&t=18901

Is it possible to add the features? Am I simply too ambitious? Perhaps, the 
features are ready but I am missing something, aren't I?

Best regards,
C. H. D.
