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
  • whereas {{#expr:1200004round-1}} → 1200000, even though {{#expr:1300004round-1}} → 1300000 (see m:Help:Format produced by expr)
• {{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}} → 123,456,789.0123500000
• {{rnd|.0001234567890123456789|20}} → 0.00012345678901235

Internal details

The template calls Template:Rnd/b1 if the number, after rounding, is positive, Template:Rnd/b-1 if it is negative, and Template:Rnd/b0 if it is zero.

Their first parameter is the rounded number, their second the rounding parameter, and their third the value of the condition that the rounding parameter is positive.
