Template:Rounddown/doc

This template rounds down a numeric value to a limited number of decimal places.

Usage

 * value
 * value decimals
 * Both parameters can be any valid numeric expression; however, decimals should be an integer.
 * The decimals parameter defaults to 0.
 * decimals can be negative to round down to a multiple of a power of ten.
 * NAN may be returned if very large values are used.

Note

 * You should use the parser function  value  rather than  value  or  value . This template should only be used when rounding down to some number of decimal places other than zero.
