This templates rounds parameter 1 to the number of digits after the point optionally given as parameter 2. If parameter 2 is negative, rounding is to a multiple of 10. If parameter 2 is undefined, numbers with 4 digits before the point are rounded to integers, numbers with 3 digits before the point are rounded to 1 digit after the point, numbers with 2 digits before the point are rounded to 2 digits after the point, and numbers with 1 digit before the point or none are rounded to 3 digits after the point.
In other words, if parameter 2 is undefined, rounding is to 4 significant digits, except that it is not cruder than rounding to an integer and not finer than rounding to three digits after the decimal point.
Examples:
"{{round|123.456|4}}" gives "123,4560"
"{{round|123.456|3}}" gives "123,456"
"{{round|123.456|2}}" gives "123,46"
"{{round|123.456|1}}" gives "123,5"
"{{round|123.456|0}}" gives "123"
"{{round|123.456|-1}}" gives "120"
"{{round|123.456|-2}}" gives "100"
"{{round|123.456|-3}}" gives "0"
"{{round|123456.789}}" → "123.457"
"{{round|12345.6789}}" → "12.346"
"{{round|1234.56789}}" → "1.235"
"{{round|123.456789}}" → "123"
"{{round|12.3456789}}" → "12"
"{{round|1.23456789}}" → "1"
"{{round|.123456789}}" → "0"
"{{round|.0123456789}}" → "0"
"{{round|.00123456789}}" → "0"
Note that trailing zeros are not shown, so rounding can seem cruder than has actually been applied:
"{{round|123.04}}" → "123"
"{{round|12.304}}" → "12"
"{{round|1.2304}}" → "1"
While this is a limitation of the template (normally there would be trailing zeros to show the precision), there is also the general problem that if a number is an integer with trailing zeros, then the precision is not clear:
This templates rounds a value to the optionally given number of digits after the point.

Number of digits after the point. If negative, rounding is to a multiple of 10. If undefined, numbers with 4 digits before the point are rounded to integers, numbers with 3 digits before the point are rounded to 1 digit after the point, numbers with 2 digits before the point are rounded to 2 digits after the point, and numbers with 1 digit before the point or none are rounded to 3 digits after the point.
