<!-- PLEASE ADD CATEGORIES AND INTERWIKIS AT THE BOTTOM OF THIS PAGE. -->
==Usage==
This template rounds parameter 1 by parameter 2 decimal places (goes the other way for negative rounding) and includes trailing zeros.
::: {{<code>'''rnd'''|54.376|2</code>}} &nbsp; &nbsp; gives {{rnd|54.376|2}}
(contracted; show full)

The [[Lua script|Lua]]-based version of <nowiki>{{rnd}}</nowiki> uses [[Module:Math]] and always has an expansion depth of 3. However, the markup-based version has an expansion depth of 9–15, which depends on the size of the numbers (integer results use depth 9, decimals use depth 12), where astronomical numbers can hit expansion depth of 15 levels, for <nowiki>{{rnd|56.44e33|-32}}</nowiki>&nbsp;&rarr; 5.64&nbsp;× 10<sup>34</sup>.
