Re^2: String to Hex

[blazar]

Update: Unstruck on advice ;)

I also agree that it deserved being unstruck. But:

• I would $num >>= 32;
• AIUI from earlier posts by knowledgeable people, the technique is valid for numbers such that the loop will always involve one or at most two iterations of the loop.

Update: s/16/32/ applied above, thanks GF.
