From English Wikipedia @ Freddythechick
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.
