Aug 30, 2024 · \vert is a synonym for | and both produce the same symbol, but should be used in the context of an ordinal, and should be used as an operator, not as a delimiter (p54, bottom). \divides once again produces the same symbol but should be used as a binary “divides” operator .

Nov 23, 2018 · \left\vert a \right\vert Now the problem. I could easily write: \vert a \vert But in case when instead of 'a' there is some large expression, the vertical lines will not be tall as the expression, but stay the small. That is what \left and \right are for. Is there any easy way to do this that I don't see here, or do I need to parse the MathML ...

Oct 3, 2019 · In short, \bigl\vert <some math atom> \bigr\vert is definitely better than \big\vert <some math atom> \big\vert, typographically speaking, as it produces the correct spacing in all cases. A final remark, prompted by a comment from barbara beeton: For the code examples used here, it's not necessary to increase the size of the vertical bars.

Nov 7, 2017 · The math versions include \vert, |, and \mid. Lastly, variants can be applied to \vert and | in the form of \big , \bigg , \Big , and \Bigg ; however, this will mess up line spacing when used inline.

@VincentNivoliers - Note that \Vert is equivalent to \|. The l and r prefixes inform TeX that the commands \lVert and \rVert should be given math codes mathopen and mathclose, respectively. (TeX has no way of knowing how to modify the default math code of \Vert.) –

Also, you have $\vert$ and $\Vert$. Since you mention using a vertical bar as a binary relation, you may want $\mid$ which is kerned to sit midway between its neighbours. But that has no double-bar version so finally, you have the option of $\mathrel{\Vert}$ which is both double-bar and kerned to the centre.

The symbol \big\lVert is as big as \Big\lVert with the Stix Two fonts. Is this a bug in the font itself, and is there a suitable workaround?

Sep 30, 2019 · I would like to declare a paired delimiter for a "triple norm". A answer to this question already exists (cf. Spacing between triple vertical lines), however, as I'm already using mathtools'
