Usage
[édit sumber]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}}gives 54,38{{Round|54.376|-1}}gives 50{{Round|68.4273E12|-10}}gives 6,843×1013
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 1×109, or less than 1×10−4.
Examples:
{{Round|2.0004|3}}gives 2,000- whereas
{{#expr:2.0004 round 3}}gives 2
- whereas
{{Round|0.000020004|7}}gives 000{{Round|0|8}}gives 0,00000000{{Round|154268|-3}}gives 154.000{{Round|154568|-3}}gives 155.000- Citakan:Xpsoc

As with #expr, the total number of significant digits is not more than 14:
- The second parameter, precision, shoulld be an integer. Non-integer may give unexpected result.
Internal details
[édit sumber]The markup-based version of Template:Round uses three subtemplates:
- {{Round/-}} — for trailing zeros
- {{Round/e+}} — for scientific notation for numbers greater than or equal to 109 or less than or equal to −109
- {{Round/e−}} — for scientific notation for numbers greater than −10−4 and less than 10−4 but not equal to zero
The Lua-based version of {{Round}} uses Module:Math and always has an expansion depth of 3. However, the markup-based version has an expansion depth of 9–15, which depends on the size of the numbers (integer results use depth 9, decimals use depth 12), where astronomical numbers can hit expansion depth of 15 levels, for {{Round|56.44e33|-32}} → 5.64 × 1034.
TemplateData
[édit sumber]Round
Rounds (parameter 1) by (parameter 2) decimal places, and formats. Scientific notation is used for numbers greater than 1×10^9, or less than 1×10^−4.
| Parameter | Keterangan | Jenis | Status | |
|---|---|---|---|---|
| number | 1 | The number to be rounded | Angka | wajib diisi |
| decimal places | 2 | The number of decimal places, if negative the number is rounded so the last (parameter 2) digits are zero | Angka | wajib diisi |
