This template is used on approximately 283,000 pages.
To avoid major disruption and server load, any changes should be tested in the template's /sandbox or /testcases subpages, or in your own user subpage. The tested changes can be added to this page in a single edit. Consider discussing changes on the talk page before implementing them.

Usage[alilan ya ing pikuwanan]

This template rounds parameter 1 by parameter 2 decimal places (goes the other way for negative rounding) and includes trailing zeros.

Template:Tlc gives 54.38
Template:Tlc gives 50
Template:Tlc 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 1Template:E, or less than 1Template:E.

Examples:

Template:Tlc gives 2.000
- whereas {{#expr:2.0004 round 3}} gives 2
Template:Tlc gives 000
Template:Tlc gives 0.00000000
Template:Tlc gives 154,000
Template:Tlc gives 155,000

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[alilan ya ing pikuwanan]

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 Template:Tlc 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 Template:Tlc → 5.64 × 10³⁴.

TemplateData[alilan ya ing pikuwanan]

Template:TemplateDataHeader

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.

Template parameters[Edit template data]
Parameter		Description	Type	Status
number	`1`	The number to be rounded	Number	required
decimal places	`2`	The number of decimal places, if negative the number is rounded so the last (parameter 2) digits are zero	Number	required
