Template:Round/doc

Usage
This template rounds parameter 1 by parameter 2 decimal places (goes the other way for negative rounding) and includes trailing zeros. 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, or less than 1.

Examples
As with #expr, the total number of significant digits is not more than 14:
 * whereas →, even though   →  (see m:Help:Format produced by expr)
 * whereas →, even though   →  (see m:Help:Format produced by expr)
 * whereas →, even though   →  (see m:Help:Format produced by expr)

 * whereas →, even though   →  (see m:Help:Format produced by expr)
 * whereas →, even though   →  (see m:Help:Format produced by expr)


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


 * Non-numeric input will result in an error message.
