== الاستخدام ==
This template rounds {{{1}}} to {{{2}}} decimal places (goes the other way for negatives) and includes trailing zeros. Scientific notation is used for numbers greater than or equal to 1{{*10^|9}}, or less than 1{{*10^|−4}}.

Compare:
*{{<code>rnd|2.0004|3</code>}} gives {{rnd|2.0004|3}}
**whereas {{<code>#expr:2.0004 round 3</code>}} gives {{#expr:2.0004 round 3}}
*{{<code>rnd|0.000020004|7</code>}} gives {{rnd|0.000020004|7}}
*{{<code>rnd|0|8</code>}} gives {{rnd|0|8}}
*{{<code>rnd|154268|-3</code>}} gives {{rnd|154268|-3}}
*{{xpsoc|rnd|1200004|-1}}
**whereas {{xpsoc|#expr:1200004round-1}}, even though {{xpsoc|#expr:1300004round-1}} (see [[m:Help:Format produced by expr]]) 
*{{xpsoc|rnd|1300004|-1}}
*{{xpsoc|rnd|4.1e6|9}}
*{{xpsoc|rnd|4.1e6|10}}
*{{xpsoc|rnd|1542689271|-7}}
*{{xpsoc|rnd|1542689271|2}}
*{{xpsoc|rnd|7e9|-9}}
*{{xpsoc|rnd|-123|1}}
*{{xpsoc|rnd|-1200007|-2}}
*{{xpsoc|rnd|-1234567899|-7}}
As with #expr, the total number of significant digits is not more than 14:
*{{xpsoc|rnd|1234567890.123456789|10}}
*{{xpsoc|rnd|123456789.0123456789|10}}
*{{xpsoc|rnd|.0001234567890123456789|20}}

== Internal details ==
The template uses three subtemplates:
*{{قا|rnd/-}} — for trailing zeros
*{{قا|rnd/e+}} — for scientific notation for numbers greater than or equal to 10<sup>9</sup> or less than or equal to −10<sup>9</sup>
*{{قا|rnd/e−}} — for scientific notation for numbers greater than −10<sup>−4</sup> and less than 10<sup>−4</sup> but not equal to zero
