==Usage==<br />
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{{e|9}}, or less than 1{{e|−4}}.<br />
<br />
Compare:<br />
*{{<code>rnd|2.0004|3</code>}} gives {{rnd|2.0004|3}}<br />
**whereas {{<code>#expr:2.0004 round 3</code>}} gives {{#expr:2.0004 round 3}}<br />
*{{<code>rnd|0.000020004|7</code>}} gives {{rnd|0.000020004|7}}<br />
*{{<code>rnd|0|8</code>}} gives {{rnd|0|8}}<br />
*{{<code>rnd|154268|-3</code>}} gives {{rnd|154268|-3}}<br />
*{{xpsoc|rnd|1200004|-1}}<br />
**whereas {{xpsoc|#expr:1200004round-1}}, even though {{xpsoc|#expr:1300004round-1}} (see [[m:Help:Format produced by expr]]) <br />
*{{xpsoc|rnd|1300004|-1}}<br />
*{{xpsoc|rnd|4.1e6|9}}<br />
*{{xpsoc|rnd|4.1e6|10}}<br />
*{{xpsoc|rnd|1542689271|-7}}<br />
*{{xpsoc|rnd|1542689271|2}}<br />
*{{xpsoc|rnd|7e9|-9}}<br />
*{{xpsoc|rnd|-123|1}}<br />
*{{xpsoc|rnd|-1200007|-2}}<br />
*{{xpsoc|rnd|-1234567899|-7}}<br />
As with #expr, the total number of significant digits is not more than 14:<br />
*{{xpsoc|rnd|1234567890.123456789|10}}<br />
*{{xpsoc|rnd|123456789.0123456789|10}}<br />
*{{xpsoc|rnd|.0001234567890123456789|20}}<br />
<br />
==Internal details==<br />
The template calls [[Template:Rnd/b1]] if the number, after rounding, is positive, [[Template:Rnd/b-1]] if it is negative, and [[Template:Rnd/b0]] if it is zero.<br />
<br />
Their first parameter is the rounded number, their second the rounding parameter, and their third the value of the condition that the rounding parameter is positive.<br />
