NAME ^

Bit::Vector::Array - Perl extension for manipulating bit vectors as an array

SYNOPSIS ^

        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

DESCRIPTION ^

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;

EXPORT

The bva routine is exported. This is used to create a new bit vector array.

        bva(my @arr_name);
