That would be true if all strings were hex numbers, but "/Some/Arbitrarily/long/string" (see Re^2: Add 1 to an arbitrary-length binary string) doesn't look like a hex number to me... Shouldn't `"61FF" + 1 = "61FG"` ? If a set of test cases were provided, that could clarify the matter.	[reply] [d/l]

Shouldn't "61FF" + 1 = "61FG" ? In short, the string "\x61\xFF" gets incremented to "\x62\x00" ... which seems a reasonable way to do it. Perhaps this is already clear (either implicitly or explicitly) from what others have provided to this thread. Cheers, Rob	[reply]

I'm not talking about the string produced by `"61FF"` but the string produced by `"a\xFF"`, which is a weird and apparently confusing way of referring to the hex number 61FF.	[reply] [d/l] [select]

actually since this is a range bound, the truncation is fine	[reply]
