Center-aligned fractions in a left-aligned formula

Postby Pepe-CH » Sun Mar 03, 2013 12:03 am

Hi

I'm looking for a better solution for this situation:

I need all my formulas left-aligned. But with fractions I prefer, when numerator and denominator are centered to the fraction bar.

So far I formated every single fraction with the alignc command:
Code: Select all   Expand viewCollapse view
A = {alignc BB} over CCCC newline
CCCC = BB over {alignc A}

And I had allways to check, if the numerator or the dnominator is smaller, and the smaller part needed the alingc command to make it centered to the fraction bar.

So my question is:
Does somebody knows a better way? May be a command which has only be written once for a line?

Cheers

I cannot say it's better, but maybe easier ;) Let the alignment to centred and use one Math object for each line, instead of one object with several newline commands.

I agree, it seems like a clunky design. I don't know of any way to make it "just work".

Maybe ... set the global (menu) alignment to centered, then ...

{alignl A} = BB over CCCC newline
{alignl CCCC} = BB over A

Thanks for the the answers and solutions so far.

This is bad news, but I feared that.

Good idea! Better one command in the beginning as having to "fix" every single fraction.
This approach generated a new idea:

If it doesn't matter to have a small gap at the left border,
also this is a possible solution:
  • Set the global alignment in the menu to centered and then ...

    "" A = BB over CCCC newline
    "" CCCC = BB over A
With this empty text (with quote signs) at the beginning of the line, the complete line is left-aligned, but the numerator and denominator stay centered to the fraction bar.
