Re^4: Trying to translate overflowing JS code to Perl

return unpack( "l", pack "L", ($value & 0xffffffff)))

For which finite numeric values do any of the following 3 renditions differ:

say unpack( "l", pack "L", ($value & 0xffffffff));
say unpack( "l", pack "L", ($value));
say unpack( "l", pack "l", ($value));

Sorry ... I'm not trying to be critical ... not even nitpicking ... but I haven't found any such values, and I'm genuinely curious as to whether they exist.)

Cheers,
Rob

Yeah - I wasn't sure either. Reconsidering, I think `pack "L"` and `pack "l"` both truncate the value to 32 bits already, so masking out higher bits does not make a difference.	[reply] [d/l] [select]
