| 8 File Name: 15.7.1.js | |
| 9 ECMA Section: 15.7.1 The Number Constructor Called as a Function | |
| 10 15.7.1.1 | |
| 11 15.7.1.2 | |
| 12 | |
| 13 Description: When Number is called as a function rather than as a | |
| 14 constructor, it performs a type conversion. | |
| 15 15.7.1.1 Return a number value (not a Number object) | |
| 16 computed by ToNumber( value ) | |
| 17 15.7.1.2 Number() returns 0. | |
| 18 | |
| 19 need to add more test cases. see the testcases for | |
| 20 TypeConversion ToNumber. | |
