I like the idea of value types, but I wonder if, for terminating decimal
numbers, the .valueOf() method from Object.prototype might be sufficient
for many operations.
Example:
function SmallDecimal(k) {
this.__value__ = k;
}
SmallDecimal.prototype.valueOf = function() {
return this.__value__.toString(10);
}
var x = new SmallDecimal(2);
var y = new SmallDecimal(3);
[x < y, x > y, x == y, x <= y, x >= y, x != y]
/*
true,false,false,true,false,true
*/
I still want to see value types go forward: in the above example, x + y
would result in "23", where x - y === -1. Perhaps .valueOf could be used
in testing simple value types implementations.
