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 2٫000- whereas {{
#expr:2.0004 round 3}} gives 2
- whereas {{
- {{
rnd|0.000020004|7}} gives 2٫00×10−5 - {{

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
