The [[Class]] property is 36 set to "Number". The [[Value]] property of the 37 newly constructed object is set to ToNumber(value) 38 39 15.7.2.2 new Number(). same as in 15.7.2.1, except 40 the [[Value]] property is set to +0. 41 42 need to add more test cases. see the testcases for 43 TypeConversion ToNumber. 44 45 Author: christine (at) netscape.com 46 Date: 29 september 1997 47 */ 48 49 var SECTION = "15.7.2";
