+ 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).
