Template:Round
0
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.

Note that trailing zeros are not shown, so rounding can seem cruder than has actually been applied:
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:

- {{rounddown}}
- {{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"
