[Dynapi-Help] which is better?? non DynAPI

Hey guys,

last week I asked about a better way of getting hex values and R.B. told me about src\lib\dynapi\ext\functions.js (thank you for the tip :).

this was the function I wanted:

DecToHex : function(val)

{
  lo=val%16
  val-=lo
  lo+=48
  if (lo>57) lo+=7

  hi=val/16
  hi+=48
  if (hi>57) hi+=7

return String.fromCharCode(hi,lo)
}

now after a little research I've found the toString() method but Im not sure about which is better, actually I got this function:

function DecToHex(w)

{

return (w < 16)? '0' + w.toString(16) : w.toString(16);

}

So I want to know which is better, I mean speed, resources...

theres something about that method Im should know??

Im trying to learn about javascript behavior, I've had some experience with it; but there are some issues that Im still not sure about them.

Example:

is x >> 4 faster than x / 16?? (as in C)

is there a document somewhere I should read??

Ok, thats my question :)

I know this is not a DynAPI issue; but DynAPI is one of the better "nice coded" scripts I've found!!

thank you all.
