    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.  On the other hand, it
-uses the 'typeof()' function (*note Type Functions::), which is specific
