NumBlk/doc

This template creates a numbered block which is usually used to number mathematical formulae.

Parameter

Parameters {{{1}}}, {{{2}}}, and {{{3}}} of this template are required. In addition, there are two optional parameters {{{RawN}}} and {{{LnSty}}}.
{{{1}}}: Specify indentation. The more colons (:) you put, the further indented the block will be. This parameter can be empty if no indentation is needed.
{{{2}}}: The body or content of the block.
{{{3}}}: Specify the block number.
{{{RawN}}}: Assigned with a non-empty or non-whitespaced string to remove the formatting on the number and the parentheses surround the number.
{{{LnSty}}}: Specify the line style. {{{Border}}}: If set, put a box around the equation. (Experimental.)

Work with float

Numbered blocks should be able to be placed around images that take up space on the left or right side of the screen. To ensure numbered block has access to the entire line, consider using a {{clear}}-like template.

Table caveat

Put {{NumBlk}} within a table yields nested table because {{NumBlk}} itself is implemented as a table. Due to a bug in Mediawiki, {{NumBlk}} must be used carefully inside tables. In particular, when indentation for outer table is desired, use explicit <dl><dd> and </dl> </dd> tags instead of using colon (:) to indent.

For example,

<dl><dd>
{|
|<math>(f * g)[n]\,</math>      
|{{NumBlk||<math>\stackrel{\mathrm{def}}{=}\sum_{m=-\infty}^{\infty} f[m]\cdot g[n - m]\,</math>|
3=<font color=darkred>'''(Eq.1)'''</font>|RawN=.}}
|-
|
|<math>= \sum_{m=-\infty}^{\infty} f[n-m]\cdot g[m].\,</math>       ([[Convolution#Commutativity|commutativity]])
|}
</dd></dl>

produces

[math](f * g)[n]\,[/math]

[math]= \sum_{m=-\infty}^{\infty} f[n-m]\cdot g[m].\,[/math]       (commutativity)

which gives the same indentation as a single colon (:). For another example,

<dl><dd>
<dl><dd>
{|
|-
|The first parameter for indentation still works when used inside table.
