   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

   For ToNumber applied to the String type, see test 9.3.1.
