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}} → 54.38
  • {{Round|54.376|-1}} → 50
  • {{Round|68.4273E12|-10}} → 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}} → 2.000
  • {{Round|0.000020004|7}} → 000
  • {{Round|0|8}} → 0.00000000
  • {{Round|154268|-3}} → 154,000
  • {{Round|154568|-3}} → 155,000
  • {{Round|1200004|-1}} → 1,200,000
  • {{Round|1300004|-1}} → 1,300,000
  • {{Round|4.1e6|9}} → 4,100,000.000000000
  • {{Round|4.1e6|10}} → 4,100,000.0000000000
  • {{Round|1542689271|-7}} → 1.54×109
  • {{Round|1542689271|2}} → 1.54268927100×109
  • {{Round|7e9|-9}} → 7×109
  • {{Round|-123|1}} → −123.0
  • {{Round|-1200007|-2}} → −1,200,000
  • {{Round|-1234567899|-7}} → −1.23×109

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

  • {{Round|1234567890.123456789|10}} → 1.2345678901235×109
  • {{Round|123456789.0123456789|10}} → 123,456,789.01235
  • {{Round|.0001234567890123456789|20}} → 0.00012345678901235
The second parameter, precision, should be an integer. Non-integer may give unexpected result.
  • {{Round|1.234567}} → 1
  • {{Round|1.234567|2}} → 1.23
  • {{Round|1.234567|2.3}} → 1.2329205947231
  • {{Round|1.234567|2.7}} → 1.2350673729657
