Examples#

Each example shows this rule applied in isolation. A complete normalization profile may make additional changes.

\sum_{i=0}^{m} a_i t^i \abovewithdelims [ ] 0.8pt \int_0^1 f(x)\,dx

\genfrac{[}{]}{0.8pt}{}{\sum_{i=0}^{m} a_i t^i}{\int_0^1 f(x)\,dx}

A+B \abovewithdelims ( ) 2pt C+D

\genfrac{(}{)}{2pt}{}{A+B}{C+D}
