==Usage==
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}}.

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}}
*{{<code>rnd|154268988|-6</code>}} gives {{rnd|154268988|-6}}
**whereas {{<code>#expr:154268988 round -6</code>}} gives [[m:help:calculation#Numbers as output|either]] 1.54E+8 or 154000000
*{{xpsoc|rnd|1542689271|-7}}
*{{xpsoc|rnd|1542689271|2}}
*{{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}}

==Internal details==
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.

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.
