Template:Rounddown/doc

This is a documentation subpage for Template:Rounddown.
It may contain usage information, categories and other content that is not part of the original template page.

This template is used on approximately 2,500 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.

Note

You should use the parserfunction {{#expr:floor value}} 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.
