+deciding whether a value is numeric or not, so if it matters to you, you
+may want to add an additional check for that.
 
+   Traditionally, it has been recommended to check for numeric values
+using the test 'x+0 == x'.  This function is superior in two ways: it
+will not report that unassigned variables contain numeric values; and it
+recognizes string values with numeric contents.
