Re: Fractions below baseline in 2.3
Le 12/04/2018 à 23:13, Anders Host-Madsen a écrit : I attach two screen shots. At least in my opinion the \pi/2 is too low in the math input mode. This is on Mac. This may be a matter of spacing between the fraction bar and the character. One day I will try to understand the rules implemented in the TeXbook and compare them to what we actually do. I have been doing that for other parts (in 2.3 the spacing between characters), but it takes a lot of time to get right. JMarc
Re: Fractions below baseline in 2.3
Yes, I can see it. The issue is that the \pi in math input mode is smaller than the \pi in latex, which makes it look unbalanced in math input mode. Probably nothing to do about that.

This is on Mac.Inline image Inline image The dividing lines for the fractions both look pretty well centered to me. I think the issue may be that the \pi glyph is not as tall as the 2 glyph, so the fraction is visually asymmetric. Try f = k 3/2 and see if you still think it is off kilter. Paul

Le 12/04/2018 à 21:21, Anders Host-Madsen a écrit : It seems to me that LyX 2.3 sets fractions slightly too low compared to the baseline when entering equations. Of course once they are typeset, they move to the correct position. But in the math input mode it's almost as though fractions are in subscript mode. Anyone else noticed? I would be interested to have an example file. JMarc

I just tried a couple of equations (one inline, one display) containing fractions in 2.3.0, and they looked fine to me. I'm basing that on the dividing line between numerator and denominator being centered vertically on the line. This was on Linux Mint MATE, Qt 5.5.1. Paul

provided the \[ and \] delimiters. Within the math inset, I typed
\frac, \dfrac and \displaystyle \frac respectively, filling in the

Re: Fractions
If you select fraction then in the top box of the fraction select matrix and choose a 2x1 matrix then you get two lines on the top of the fraction. I also chose a 1x1 matrix on the bottom so the format is the same. The only draw back is that the bottom of the fraction is not left aligned. See attched.
