Usage
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 Template:Rnd- whereas {{
#expr:2.0004 round 3}} gives 2
- whereas {{
- {{
rnd|0.000020004|7}} gives Template:Rnd - {{
rnd|0|8}} gives Template:Rnd - {{
rnd|154268|-3}} gives Template:Rnd {{rnd|1200004|-1}}→ Template:Rnd- whereas
{{#expr:1200004round-1}}→ 1200000, even though{{#expr:1300004round-1}}→ 1300000 (see m:Help:Format produced by expr)

{{rnd|1300004|-1}}→ Template:Rnd{{rnd|4.1e6|9}}→ Template:Rnd{{rnd|4.1e6|10}}→ Template:Rnd{{rnd|1542689271|-7}}→ Template:Rnd{{rnd|1542689271|2}}→ Template:Rnd{{rnd|7e9|-9}}→ Template:Rnd{{rnd|-123|1}}→ Template:Rnd{{rnd|-1200007|-2}}→ Template:Rnd{{rnd|-1234567899|-7}}→ Template:Rnd
As with #expr, the total number of significant digits is not more than 14:
{{rnd|1234567890.123456789|10}}→ Template:Rnd{{rnd|123456789.0123456789|10}}→ Template:Rnd{{rnd|.0001234567890123456789|20}}→ Template:Rnd
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
