Bug
**What is the current behavior?**
React at the beginning rounds `input[type=range]` value to 0 or 1, and then looks at step parameter which is 0.1 for example. The result is incorrect value of input after component mounts. When I put `value` attribute after `step` attributes, it works fine.
**If the current behavior is a bug, please provide the steps to reproduce and if possible a minimal demo of the problem via https://jsfiddle.net or similar (template: https://jsfiddle.net/reactjs/69z2wepo/).**
Demo: https://jsfiddle.net/2Lm4gy5k/ Comment or uncomment line 13 and 14 to see the difference.

**What is the expected behavior?**
To always look at step parameter and then round the value (if required).
**Which versions of React, and which browser / OS are affected by this issue? Did this work in previous versions of React?**
v15.1.0 (Opera, Chrome, Firefox). 

Yes, works in v.0.14.0 (https://jsfiddle.net/wrcnLugd/)

var group = queryRoot.querySelectorAll(
      'input[name=' + JSON.stringify('' + name) + '][type="radio"]');
    for (var i = 0; i < group.length; i++) {
      var otherNode = group[i];
      if (otherNode === rootNode ||
          otherNode.form !== rootNode.form) {
        continue;
      }
      
      
      
      
      var otherInstance = ReactDOMComponentTree.getInstanceFromNode(otherNode);
      invariant(
        otherInstance,
        'ReactDOMInput: Mixing React and non-React radio inputs with the ' +
        'same `name` is not supported.'
      );
      
      
      
      ReactUpdates.asap(forceUpdateIfMounted, otherInstance);
    }
  }
  return returnValue;
