For at undgå store forstyrrelser og unødvendigt pres på serverne, bør alle ændringer af skabelonen først afprøves i dens tilhørende /sandkasse eller /test-undersider, eller i din egen sandkasse. De færdigafprøvede ændringer kan derefter overføres til denne side ved en enkelt redigering. Overvej venligst at diskutere alle ændringer på diskussionssiden før du implementerer dem.

Usage[redigér wikikode]

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

{{rnd|54.376|2}}     gives 54,38
{{rnd|54.376|-1}}   gives 50
{{rnd|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.

Eksempler:

  • {{rnd|2.0004|3}} giver 2,000
    • whereas {{[[Skabelon:#expr:2.0004 round 3|#expr:2.0004 round 3]]}} gives 2
  • {{rnd|0.000020004|7}} giver 2,00×10−5
  • {{rnd|0|8}} giver 0,00000000
  • {{rnd|154268|-3}} giver 154.000
  • {{rnd|154568|-3}} giver 155.000
  • {{rnd|1200004|-1}} → 1.200.000
  • {{rnd|1300004|-1}} → 1.300.000
  • {{rnd|4.1e6|9}} → 4.100.000,000000000
  • {{rnd|4.1e6|10}} → 4.100.000,0000000000
  • {{rnd|1542689271|-7}} → 1,54×109
  • {{rnd|1542689271|2}} → 1,54268927100×109
  • {{rnd|7e9|-9}} → 7×109
  • {{rnd|-123|1}} → −123,0
  • {{rnd|-1200007|-2}} → −1.200.000
  • {{rnd|-1234567899|-7}} → −1,23×109

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

  • {{rnd|1234567890.123456789|10}} → 1,2345678901235×109
  • {{rnd|123456789.0123456789|10}} → 123.456.789,01235
  • {{rnd|.0001234567890123456789|20}} → 0,00012345678901235

Internal details[redigér wikikode]

The markup-based version of Template:rnd uses three subtemplates:

  • {{rnd/-}} — for trailing zeros
  • {{rnd/e+}} — for scientific notation for numbers greater than or equal to 109 or less than or equal to −109
  • {{rnd/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 {{rnd}} uses Modul: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 {{rnd|56.44e33|-32}} → 5.64 × 1034.

TemplateData[redigér wikikode]

Dette er TemplateData-dokumentationen til denne skabelon, brugt af VisualEditor og andre værktøjer.

Rnd

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.
