Hi monks,
I received a binary string on twitter, and I translated it into words in perl:
my $string="01100110 01100101 01100101 01101100 01101001 01101110 0110
+0111 00100000 01101100";
#$string=~ s/ (\d+)/pack('B8', $1)/egx; # way 1
$string=~ s/ (\d+)/chr(oct('0b'.$1))/egx; # way 2
My question is why perl do not support
chr('0b'.$1) #it will throw a error message: Argument "0b01100110 " is
+n't numeric
Thanks very much!
UPDATE:
I mean, I know I should pass a number to chr, but is there a way to convert a string to number explicitly like perl6?
+('0b'~'0111011') #perl6
I am trying to improve my English skills, if you see a mistake please feel free to reply or /msg me a correction
