Re: emulate 32-bit on perl 64

How can I force it to work correct on perl based 64 ?

It gets very messy.

Effectively you have to mask the resultant from operation after any operation that might cause the resultant to be promoted to more than 32 bits. eg.

C:\test>\perl32\bin\perl -le"print 11 | 29 | ~15"
4294967295

C:\test>\perl64\bin\perl -le"print 11 | 29 | ~15"
18446744073709551615

C:\test>\perl64\bin\perl -le"print 11 | 29 | ( ~15 & 0xffffffff )"
4294967295

And if you are manipulating signed rather than unsigned values it gets really tiresome.

I don't know of a good solution to this problem.

With the rise and rise of 'Social' network sites: 'Computers are making people easier to use everyday'

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

"Science is about questioning the status quo. Questioning authority".

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

The start of some sanity?
