  org.ucl.xpath.function.Function
      org.ucl.xpath.function.FnFloor

public class FnFloor

extends Function

Returns the largest (closest to positive infinity) number with no fractional part that is not greater than the value of $arg. If type of $arg is one of the four numeric types xs:float, xs:double, xs:decimal or xs:integer the type of the return is the same as the type of $arg. If the type of $arg is a type derived from one of the numeric types, the type of the return is the base numeric type. For float and double arguments, if the argument is positive zero (+0), then positive zero (+0) is returned. If the argument is negative zero (-0), then negative zero (-0) is returned.
