How many bytes does Perl use for integers?

How many bytes does Perl use for integers?

(OP)
How many bytes does Perl use for standard integers?  Could anyone also answer why
printf ("%u", -455); yields 4294966841?

Thank you

RE: How many bytes does Perl use for integers?

An integer is 2^32.  The signed range is -2147483648 to 2147483647. The unsigned range is 0 to 4294967295. Since %u is unsigned, subtracting 455 from 0 would result in max(unsigned int) - 454 = 4294966841.

It's true for C/C++, which is the basis for Perl.  I believe it is the same across all platforms.

There, I got a userid.  It seemed like too much trouble and I didn't really want to get sucked into another forum, but too late.
