ढाँचा:Round

Template documentation[view] [edit] [history] [purge]

Usage

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 ५४.३८
• {{Round|54.376|-1}}   gives ५०
• {{Round|68.4273E12|-10}} gives ६.८४३×10^१३

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 1×10^९, or less than 1×10⁻⁴.

Examples:

• {{Round|2.0004|3}} gives २.000
  • whereas {{#expr:2.0004 round 3}} gives 2
• {{Round|0.000020004|7}} gives २.00×10^−५
• {{Round|0|8}} gives ०.00000000
• {{Round|154268|-3}} gives १५४,०००
• {{Round|154568|-3}} gives १५५,०००
• {{Round|1200004|-1}} → १,२००,०००
  • whereas {{#expr:1200004round-1}} → 1200000, even though {{#expr:1300004round-1}} → 1300000 (see m:Help:Format produced by expr)
• {{Round|1300004|-1}} → १,३००,०००
• {{Round|4.1e6|9}} → ४,१००,०००.000000000
• {{Round|4.1e6|10}} → ४,१००,०००.0000000000
• {{Round|1542689271|-7}} → १.५४×10^९
• {{Round|1542689271|2}} → १.५४२६८९२७१00×10^९
• {{Round|7e9|-9}} → ७×10^९
• {{Round|-123|1}} → −१२३.0
• {{Round|-1200007|-2}} → −१,२००,०००
• {{Round|-1234567899|-7}} → −१.२३×10^९

As with #expr, the total number of significant digits is not more than 14:

• {{Round|1234567890.123456789|10}} → १.२३४५६७८९०१२३५×10^९
• {{Round|123456789.0123456789|10}} → १२३,४५६,७८९.०१२३५
• {{Round|.0001234567890123456789|20}} → ०.०००१२३४५६७८९०१२३५

The second parameter, precision, shoulld be an integer. Non-integer may give unexpected result.

• {{Round|1.234567}} → १
• {{Round|1.234567|2}} → १.२३
• {{Round|1.234567|2.3}} → १.२३२९२०५९४७२३१
• {{Round|1.234567|2.7}} → १.२३५०६७३७२९६५७

Internal details

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.

Roundको ढाँचातथ्याङ्क

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

Parameter		विवरण	प्रकार	स्थिति
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
