==Usage==
Like {{tl|rnd}}, this template rounds {{{1}}} to {{{2}}} decimal places (goes the other way for negatives) and includes trailing zeros.  Also like {{tlf|rnd}}, scientific notation is used for numbers whose absolute value is greater than or equal to 1{{e|9}}, or less than 1{{e|−4}}.  It differs from {{tlf|rnd}} in that it uses thin gaps to delimit numbers like {{tl|val}} (see also {{tl|gaps}}).

Examples:
*{{xpsoc|rndgaps|2.0004|3}}
*{{xpsoc|rndgaps|0.000020004|7}}
*{{xpsoc|rndgaps|0|8}}
*{{xpsoc|rndgaps|154268|-3}}
*{{xpsoc|rndgaps|1200004|-1}} 
*{{xpsoc|rndgaps|1300004|-1}}
*{{xpsoc|rndgaps|4.1e6|9}}
*{{xpsoc|rndgaps|4.1e6|10}}
*{{xpsoc|rndgaps|1542689271|-7}}
*{{xpsoc|rndgaps|1542689271|2}}
*{{xpsoc|rndgaps|7e9|-9}}
*{{xpsoc|rndgaps|-123|1}}
*{{xpsoc|rndgaps|-1200007|-2}}
*{{xpsoc|rndgaps|-1234567899|-7}}

As with #expr, the total number of significant digits is not more than 14:
*{{xpsoc|rndgaps|1234567890.123456789|10|nocategory=1}}
*{{xpsoc|rndgaps|123456789.0123456789|10}}
*{{xpsoc|rndgaps|.0001234567890123456789|20|nocategory=1}} 

==Internal details==
The template uses the following.
*{{tl|val/delimitnum/fraction}} — for trailing zeros
*{{tl|rndgaps/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>
*{{tl|rndgaps/e−}} — for scientific notation for numbers greater than −10<sup>−4</sup> and less than 10<sup>−4</sup> but not equal to zero

*{{tl|rndnear}}
