\mid, | (vertical bar), \vert, \lvert, \rvert, \divides - TeX According to texdoc symbols: \mvert and \mid are identical and produce a relation \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 \lvert and \rvert are left and right
math mode - Use `\big\vert f (x) \big\vert` or `\big\lvert f (x) \big . . . 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
Spacing between triple vertical lines - LaTeX Stack Exchange For the MWE below, I've actually set the spacing between the vertical bars to be slightly less than what's generated by \[l,r]Vert -- you can adjust the spacing to suit your taste by changing the value of the argument of the four \kern commands
Double vertical bar notation - TeX - LaTeX Stack Exchange 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
Using \big| and \right| versus \bigr\rvert and \right\rvert - TeX I would think that anytime one used a vert bar to delimit on the right they should write \rvert, \bigr\rvert, etc , or \right\rvert (or \mright\rvert) However, I feel like I am seeing these mixed and matched in some answers
How to draw a vertical line of desired length in equations. I am writing a big formula where a vertical line is needed Instead of $\\vline$ or $|$, does anyone know a way to draw this vertical line of desired length? The formula is something like $$ E\\Bigg
Why does \big\mid not work? - TeX - LaTeX Stack Exchange 26 The commands \bigl\vert, \bigm\vert, and \bigr\vert are semantically symmetric Incidentally, the triplets of commands \bigl\lvert \bigl\vert \big\lvert and \bigr\rvert \bigr\vert \big\rvert, respectively, produce the same output It's the command \mid that's a bit of an outlier, semantically speaking
stix - `\big\lVert` is too big - TeX - LaTeX Stack Exchange 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? MWE (run in lualatex): \documentclass {minimal} \usepac
\mid or \vert in a conditional expectation or density function? The vertical bar produced by | or \vert has TeX math type "ordinary", meaning that no special meaning is attached to it Quite often, though, it's necessary to inform TeX that the bar does have a special meaning If the bar acts as a separator between some expression and the conditioning event, as in "the conditional density of Y given x", you should use \mid: doing so generates a vertical bar
