قالب:Rounddown/doc

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.
