Re^2: Bit manipulation of a bit stream to generate different elements of an array with each nibble taking either 0 or 1 in perl

Thanks for the solution. I am actually new to perl and just came up with that weird way to get that output. ;-) But I think the answer is in decimal. After getting these output I added that to an array using the following code push @strobes,$x; But after that I want to AND(logical) it using a given value. Eg. 00001111--->(offset 3)---> 00001000 11111111--->(offset 2)---> 11111100 I tried to perform any operation on these values but it's treating the values as decimal eg. 00001110-1=1109 Any suggestion on how to perform the logical AND operation.

printf "Hex notation: %x AND %x = %x\n", $N1, $N2, $N1_AND_N2;
