hasOwnProperty in updated format float breaks IE8 and below

IE8 and below don't seem to support hasOwnProperty for host objects according to this: http://stackoverflow.com/a/8159434
As a result, 

``` javascript
var i,
  t = table && table.hasOwnProperty('config') ? table.config.usNumberFormat !== false :
    typeof table !== "undefined" ? table : true;
```

throws
Object doesn't support property or method 'hasOwnProperty'
