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 , 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 ), there is also the general problem that if a number is an integer with trailing zeros, then the precision is not clear:
-
"{{round|1230.4}}"→ "1.230"

- {{ decimals }} – acts like rounding but displays trailing zeros after the decimal point
- {{ precision }} – handles rounding of large numbers, too, like "349,030,293" → "349,030,000", "349,000,000", or "350,000,000"

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.
