"Template:Leftdelimiter" and "Template:Leftdelimiter/doc" redirect to here.
This is for producing tall left-handed delimiters for multiline expressions (usually mathematical) in HTML, together with ((rdelim )), compatible with ((math )), as an alternative to LaTeX. Up to 5 lines are possible. The name "ldelim" is a shorthand for "left-handed delimiter".
This template uses ((delimiter-es )) .
The template has the code:
((ldelim|a|b|sup=|sub=))
containing two parameters:
the first parameter a
is
square for square brackets [ ],
round for round brackets ( ),
vert for vertical bars | |,
doublevert for double vertical bars || ||,
the second parameter b
is the number of lines for the expression, and equals one of the values 2, 3, 4, 5 .
and two optional parameters:
sup for superscripts outside of the delimiter,
sub for subscripts outside of the delimiter.
Without the superscript and subscript parameters, the < sup >
or < sub >
tags alone will not position the superscripts or subscripts correctly.
