I misspoke, slightly:
$temp = ~s/'//g;
the s/// is working on the current $_ and then taking the binary negation
(perldoc perlop):
Unary "~" performs bitwise negation, i.e., 1âs complement. For example,
"0666 & ~027" is 0640. (See also "Integer
Arithmetic" and "Bitwise String Operators".) Note that the width
of the result is platform-dependent: ~0 is 32 bits
wide on a 32-bit platform, but 64 bits wide on a 64-bit platform,
so if you are expecting a certain bit width, remember
to use the & operator to mask off the excess bits.
and that - so '4294967295' is probably the binary negation of zero unless
you happen to have something in $_. Nope:
$ perl -e 'print ~4294967295'
0
a
