الاستخدام

This template rounds {{{1}}} to {{{2}}} decimal places (goes the other way for negatives) and includes trailing zeros. Scientific notation is used for numbers greater than or equal to 1×109, or less than 1×10−4.

Compare:

  • {{rnd|2.0004|3}} gives 2٫000
    • whereas {{#expr:2.0004 round 3}} gives 2
  • {{rnd|0.000020004|7}} gives 2٫00×10−5
  • {{rnd|0|8}} gives 0٫00000000
  • {{rnd|154268|-3}} gives 154٬000
  • {{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}} ← 1٫542689271×109
  • {{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}} ← 123٬456٬789٫0123500000
  • {{rnd|.0001234567890123456789|20}} ← 0٫00012345678901235

Internal details

The template 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
