Re: Re: Bit by a Hex String

Okay, first I need to say, I love your BC solution. It's simple, and elegant. That being said I did some playing around with BigInt, so here's the code I came up with:

sub shift_bs{
    $add = shift;
    $source = shift;
    $num1=Math::BigInt->new("0x".$source);
    $num1->blsft(1);
    $num1+=$add;
    $temp = $num1->as_hex();
    $temp =~ /0x(.*)/;
    return $1;
}
[download]

Yeah, the $add is a legacy thing, but that's okay. I want to thank you especially, because you went to quite a bit of work to come up with that code.

`$num1=Math::BigInt->new("0x".$source);` [download] Ah, I didn't know you could do that. The Math::BigInt manual page says: `Input Input values to these routines may be either Math::Big- Int objects or strings of the form "/^[+-]?[\d]+\.?[\d]E?[+-]?[\d]$/".` [download] Abigail	[reply] [d/l] [select]

Neither did I I only tried it after seeing this in the documentation: `Examples for converting: my $x = Math::BigInt->new('0b1'.'01' x 123); print "bin: ",$x->as_bin()," hex:",$x->as_hex()," dec: ",$x,"\n";` [download] == Kwyjibo. A big, dumb, balding North American ape. With no chin.	[reply] [d/l]
