[Tex/LaTex] Difference between \big[ and \bigl[


What is the difference between \big[ (or equivalently \big() and \bigl[? Is it always necessary to mention l (left) and r (right)?

Best Answer

\bigl declares an opening math delimiter with less horizontal spacing than the unspecified \big. \bigr defines a closing math delimiter. Using a \bigl and \bigr pair you could get the brackets or parentheses closer to the term within.

Just compare:

$\bigl[ \times \bigr]$

$\big[ \times \big]$
