## 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 1×10, or less than 1×10−4.

Compare:

• {{`rnd|2.0004|3`}} gives २�000
• whereas {{`#expr:2.0004 round 3`}} gives 2
• {{`rnd|0.000020004|7`}} gives २�00×10−५
• {{`rnd|0|8`}} gives ०�00000000
• {{`rnd|154268|-3`}} gives १५४,०००
• `{{rnd|1200004|-1}}` → १,२००,०००
• whereas `{{#expr:1200004round-1}}` → 1200000, even though `{{#expr:1300004round-1}}` → 1300000 (see m:Help:Format produced by expr)
• `{{rnd|1300004|-1}}` → १,३००,०००
• `{{rnd|4.1e6|9}}` → ४,१००,०००�000000000
• `{{rnd|4.1e6|10}}` → ४,१००,०००�0000000000
• `{{rnd|1542689271|-7}}` → १.५४×10
• `{{rnd|1542689271|2}}` → १.५४२६८९२७१00×10
• `{{rnd|7e9|-9}}` → ७×10
• `{{rnd|-123|1}}` → −१२३�0
• `{{rnd|-1200007|-2}}` → −१,२००,०००
• `{{rnd|-1234567899|-7}}` → −१.२३×10

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

• `{{rnd|1234567890.123456789|10}}` → १.२३४५६७८९०१२३५×10
• `{{rnd|123456789.0123456789|10}}` → १२३,४५६,७८९.०१२३५
• `{{rnd|.0001234567890123456789|20}}` → ०.०००१२३४५६७८९०१२३५

## 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.
