Hi Folks,
How do I tell that an item is a numeric atomic value?
I want to create a function, f:is-number(exp), that returns true if the value
of $exp is a numeric atomic value, false otherwise.
For example, f:is-number(3.14) should return true. If it is called with an
element that contains the value 3.14 then it should return false.
How do I determine that the value of $exp is a numeric atomic value?
/Roger
