What's the fastest way to convert any value to an octet?

Preparation code

 
<script>
  Benchmark.prototype.setup = function() {
    window.input = (-5+10*Math.random()) | 0;
    window.output = 0;
    window.data = new DataView(new ArrayBuffer(1));
    window.tarr = new Uint8Array(1);
  };
</script>

Test runner

Warning! For accurate results, please disable Firebug before running the tests. (Why?)

Java applet disabled.

window.output = +input & 255;

data.setUint8(0,input);
window.output = data.getUint8(0);

window.output = (tarr[0]=input),tarr[0];
