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
