Number Conversion Timing

Test	time	avg time	avg time-overhead	Result
Base					(pure overhead)
eval()
parseFloat()
Number()
Unary Plus

Rounds: Number String:

All tests are on the form:


  function testX(n,y) {
   var x;
   var t1 = new Date();
   for (var i=0;i<n;i++) {
     x = X(y);
   }
   var t2 = new Date();
   return t2 - t1;
  }

where X is one of nothing, eval, parseFloat, Number or unary prefix plus.
