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: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.
