Re: printf formatting 32 bit values

If you and the value with 0xffffffff, it will trim it to 32-bits:

print unpack 'Q', pack 'Q', -1;;
18446744073709551615

print unpack 'Q', pack 'Q', -1 & 0xffffffff;;
4294967295

Is that the sort of thing you are looking for?

Examine what is said, not who speaks -- Silence betokens consent -- Love the truth but pardon error.

In the absence of evidence, opinion is indistinguishable from prejudice.

Yep, that does it. The pack'ing was the part I was missing ... sign extending 0x000000000ffffffff didn't work. thank you	[reply]
