| 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). |
