Usage[muda l codesc]
This template rounds parameter 1 by parameter 2 decimal places (goes the other way for negative rounding) and includes trailing zeros.
{{Round|54.376|2}}{{Round|54.376|-1}}{{Round|68.4273E12|-10}}
For example, rounding by 1 gives 1 decimal digit, rounding by 0 gives integers, or rounding by -2 gives the amount in hundreds. Scientific notation is displayed for numbers greater than or equal to 1Template:E, or less than 1Template:E.
Examples[muda l codesc]
{{Round|2.0004|3}}- {{expr:2.0004 round 3}} → 2
{{Round|0.000020004|7}}{{Round|0|8}}{{Round|154268|-3}}{{Round|154568|-3}}{{Round|1200004|-1}}- whereas {{expr:1200004round-1}} → 1200000, even though {{expr:1300004round-1}} → 1300000 (see m:Help:Format produced by expr)
{{Round|1300004|-1}}{{Round|4.1e6|9}}{{Round|4.1e6|10}}{{Round|1542689271|-7}}{{Round|1542689271|2}}{{Round|7e9|-9}}{{Round|-123|1}}{{Round|-1200007|-2}}{{Round|-1234567899|-7}}
As with #expr, the total number of significant digits is not more than 14:
{{Round|1234567890.123456789|10}}{{Round|123456789.0123456789|10}}{{Round|.0001234567890123456789|20}}
- The second parameter, precision, should be an integer. Non-integer may give unexpected result.
{{Round|1.234567}}{{Round|1.234567|2}}{{Round|1.234567|2.3}}{{Round|1.234567|2.7}}
