lowest EXSLT math lowest minimum public domain 1 Jeni Tennison 2001-03-28 Returns the nodes with the minimum value in a node set. 1.1 Jeni Tennison 2001-04-28 Clarified the wording of the definition, highlighting the fact that a non-numeric value will result in an empty set being returned. 1.2 Jeni Tennison 2001-05-22
  • Added vendor implementations in Saxon and 4XSLT

 1.3 Jeni Tennison 2001-06-11 Added vendor implementation in jd.xslt. 1.4 Jeni Tennison 2001-08-23 Added vendor implementation in libxslt. 1.5 Craig Stewart 2002-08-20 Added Xalan-J implementation to the list. 1.6 Craig Stewart 2002-11-12 Updated 4XSLT version to 0.12.0a3.

The math:lowest function returns the nodes in the node set whose value is the minimum value for the node set. The minimum value for the node set is the same as the value as calculated by math:min. A node has this minimum value if the result of converting its string value to a number as if by the number function is equal to the minimum value, where the equality comparison is defined as a numerical comparison using the = operator.

If any of the nodes in the node set has a non-numeric value, the math:min function will return NaN. The definition numeric comparisons entails that NaN != NaN. Therefore if any of the nodes in the node set has a non-numeric value, math:lowest will return an empty node set.

The math:lowest template returns a result tree fragment consisting of copies of the nodes as returned by the function.

This use case shows an error when the function is passed a number as the value of the first argument. This use case shows an error when the function is passed a number as the value of the nodes parameter.
