I consistently find that math symbols scaled with \big
/\bigl
/\bigr
are too small and those scaled with \Big
/\Bigl
/\Bigr
are too tall. Here is an example:
\documentclass{article}
\usepackage{amsmath}
\begin{document}
\(\lvert x^2 + y^2 \rvert\)
\(\bigl\lvert x^2 + y^2 \bigr\rvert\)
\(\Bigl\lvert x^2 + y^2 \Bigr\rvert\)
\(\bigl\{ \bigl\lvert x^2 + y^2 \bigr\rvert \mathrel{\big|} 5|x \wedge 7|y \bigr\}\)
\(\Bigl\{ \bigl\lvert x^2 + y^2 \bigr\rvert \mathrel{\Big|} 5|x \wedge 7|y \Bigr\}\)
\(a/b \big/ c/d \Big/ e/f \big/ g/h\)
\end{document}
In the first line, the middle/right formulas were created with \big
and \Big
, respectively. In the second line, the left-hand set uses \big
for the set delimiters and its middle, and the right-hand set uses \Big
for them. I want something larger than \big
but not as huge as \Big
.
I'm not really asking anyone to fix this for me, which I suspect would be a nontrivial task. I am inquiring about the infrastructure for this and any possible future extensions.
\big
in the set description; rather you want to use:
instead of\mid
, if the bar for the absolute value frequently appears at its side.|
. Though a case for consistency within a document can arise, and perhaps changing everything to:
might look bad for other reasons.)
