math mode - Absolute Value Symbols - TeX - LaTeX Stack Exchange
a definite advantage of using commands like \abs and \norm which no one seems to have mentioned: since the | symbol has special meaning in the makeidx context, trying to enter terminology using a bare | within \index{...} will result in (delayed) errors and a lot of hair pulling for someone not really familiar with that usage.
math mode - Latex: Nice abs - TeX - LaTeX Stack Exchange
Though if part of the \abs macro, still other delimiters inside the \abs would be affected, so it must be explicitly reset before the #1. In my documents, I like all delimiters to grow ;-) – Stephan Lehmke
Difference between symbols for absolute value? - LaTeX Stack …
2017年10月8日 · First let's get rid of the last case: \mid is a relation symbol like = or < and TeX adds spaces around it that disqualify the command from being used for the absolute value. The other two seem good, but the first one is better as it doesn't need precautions.
how to write a limit and how to use large absolute value?
For the first question, you can typeset limits using the \lim command: $\lim_{x\to\infty}\frac{1}{x}$ \[ \lim_{x\to\infty}\frac{1}{x} \]
Absolute value symbol with spacing - LaTeX Stack Exchange
2022年2月7日 · @Mico I just thought it looked better this way, with a little less spacing. Indeed if you use {} around \cdot you will get the same spacing as if the dot was used as a binary operator, but here we use the dot as the symbol, not as the operator, so I don't see a reason why choosing the precise binary operator spacing would be better.
Providing command for absolute value - LaTeX Stack Exchange
2020年8月10日 · Hardcoding autoscalling is a disaster waiting to happen (try it on \sum_n), I'd rather recommend using \DeclarePairedDelimiter to define a better abs command (disclaimer I wrote it) – daleif Commented Aug 11, 2020 at 5:07
vertical bar for absolute value and conditional expectation
\mid when it's a relation symbol, for instance in set notation or for “divides”; \lvert or \rvert when it's a (left or right) delimiter; note that this requires amsmath that's recommended anyway when a document needs math. Just typing | can work, but there are some subtleties, so it's better to use the above commands. Similarly, for the ...
symbols - Too long/short pipe (absolute value) in math mode with ...
Using that package's features, my first cut was to create a command \myabs, which places abs bars around anything. It will stretch the size of the bars exactly to the argument. The downside of this first attempt is that you may have preferred the bars to extend a bit above and below the object being surrounded (addressed later in this answer).

2022年9月9日 · I try to write absolute value symbols and norm symbols in section. The command \\norm* and \\abs* in package physics works not well. So I use the solution in Absolute Value Symbols. But when I put this

2016年2月9日 · there is an \abs macro defined in the preamble of all the "example" files for ams document classes. (too) many people take those files and use them as the base for constructing new documents, leaving behind definitions that were there only to illustrate how to use the document classes.
