Convert vector of binaries to decimal and/or hex

I want to convert a binary string to decimal.

This converst one item of the array to an int value:

bit_vector = digits(0x0284, base=2, pad=16)
convert(Int,bit_vector[1])

but i want something like this, but it does not work.

convert(Int,bit_vector[1:4])
convert(UInt16,bit_vector[1:4])

Thank you for the help you can provide

Can you clairfy what bit_vector is?

hi @mkitti,

bit_vector is the answer of executing digits(0x0284, base=2, pad=16)

if one does typeof(bit_vector) it is of type: Vector{Int64} (alias for Array{Int64, 1})

Is evalpoly what you’re looking for?

julia> x = 0x0284
0x0284

julia> bit_vector = digits(x, base=2, pad=16)

julia> bits_to_int(bit_vector::Union{BitVector, Vector{Bool}}) =
          sum(bit_vector .<< (0:length(bit_vector)-1))
bits_to_int (generic function with 1 method)
