Re: Bitwise Operator Error

[broomduster]

Your hexadecimal number in $testString needs to begin with 0x be properly interpreted as hexadecimal. Then it will work. You can also simplify your white-space removal. All together, here is one way to get where you want to go:

$testString =~ s/\s+//g;

$testString =~ s/^/0x/;
$maskResult = $testString & 400000000000000000000000;

$maskResult = hex( $testString ) & 0x400000000000000000000000;

Updated: Need to use hex and need to have mask as hex string.

Updated 2: I see ikegami has also pointed out my error(s) corrected above.

Updated 3: and ikegami has also noted the need for Math::BigInt here.

That's wrong.

>perl -we"print 0+'0x0001'"
Argument "0x0001" isn't numeric in addition (+) at -e line 1.
0

See my reply to the OP for details

Thanks for the help but I just tried what you suggested and it doesn't seem to work. It outputs a 0 which is correct but I get a warning saying that it isn't numeric. I then changed the first bit of the original string to an F to test if I get an output of 1, and I still get a 0.
