Template:Rounddown
 | This template is used on approximately 4,100 pages and changes may be widely noticed. Test changes in the template's /sandbox or /testcases subpages, or in your own user subpage. Consider discussing changes on the talk page before implementing them. |
This template rounds down a numeric value to a limited number of decimal places.
Usage
{{Rounddown|value}}{{Rounddown|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.

{{#expr:floorvalue}}rather than{{Rounddown|value}}or{{Rounddown|value|0}}. This template should only be used when rounding down to some number of decimal places other than zero.
