/**
   File Name:          9.3-1.js
   ECMA Section:       9.3  Type Conversion:  ToNumber
   Description:        rules for converting an argument to a number.
   see 9.3.1 for cases for converting strings to numbers.
   special cases:
   undefined           NaN
   Null                NaN
   Boolean             1 if true; +0 if false
   Number              the argument ( no conversion )
   String              see test 9.3.1
   Object              see test 9.3-1


   This tests ToNumber applied to the object type, except
   if object is string.  See 9.3-2 for
   ToNumber( String object).
