Template:Rounddown

This template rounds down (aka “truncates”) a numeric value to a limited number of decimal places.

Usage

 *  
 *  
 * Both parameters can be any valid numeric expression.
 * The decimals parameter defaults to 0 and is rounded to the nearest integer.
 * decimals can be negative to round down to a multiple of a power of ten.
 * If decimals is not between -20 and 20, the value is returned without rounding.

Examples

 *   =
 *   =  (should be 0.123, not 0)
 *   =  (should be 0, not "-0")
 *   =  (should be -0.123, not 0)
 *   =


 *   =  (should be 0, not "-0")
 *  </tt> =  (should be 0, not "-1")
 *  </tt> =


 *  </tt> =
 *  </tt> =  (should be 0, not "-0")
