Hi all, Great stuff. I think there is a bug in Math.abs:

javascript-semantics/stdlib/08.math.js

Lines 5 to 11 in d5aca30

    
           Math.abs = function (x) { 
        
               x = @ToNumber(x); 
        
               if (x < 0) 
        
                   return -x; 
        
               else 
        
                   return x; 
        
           };

According to the spec, abs of -0 should be 0 not 0.

deian changed the title ~~Math.abs(-0) should be -0~~ Math.abs(-0) should be 0
