Bit::Vector::Array - Perl extension for manipulating bit vectors as an array
use Bit::Vector::Array;
bva(my @my_array);
@my_array=8; # 1000 binary. index 4 .. 1
$my_array[2]=1; # 1010 binary. bit index 2
print "vector is ".@my_array."\n"; # vector is 10
Bit::Vector::Array is used to store an integer, but access bits of that integer as a bit vector. The integer is stored by assigning to the scalar value of an array. Individual bits are accessed by indexing into the array. The bit indexes start at 1 and increase from there.
To set the least significant bit in @arr, use this: $arr[1]=1;
The bva routine is exported. This is used to create a new bit vector array.
bva(my @arr_name);
