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}}
• {{Round|54.376|-1}}
• {{Round|68.4273E12|-10}}

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}}
  • {{expr:2.0004 round 3}} → 2
• {{Round|0.000020004|7}}
• {{Round|0|8}}
• {{Round|154268|-3}}
• {{Round|154568|-3}}
• {{Round|1200004|-1}}
  • whereas {{expr:1200004round-1}} → 1200000, even though {{expr:1300004round-1}} → 1300000 (see m:Help:Format produced by expr)
• {{Round|1300004|-1}}
• {{Round|4.1e6|9}}
• {{Round|4.1e6|10}}
• {{Round|1542689271|-7}}
• {{Round|1542689271|2}}
• {{Round|7e9|-9}}
• {{Round|-123|1}}
• {{Round|-1200007|-2}}
• {{Round|-1234567899|-7}}

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

• {{Round|1234567890.123456789|10}}
• {{Round|123456789.0123456789|10}}
• {{Round|.0001234567890123456789|20}}

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

• {{Round|1.234567}}
• {{Round|1.234567|2}}
• {{Round|1.234567|2.3}}
• {{Round|1.234567|2.7}}

Non-numeric input will result in an error message.

• {{Round|invalid}}
