Functions
Split a binary at the given index.
Example
iex> TL.Binary.binary_split <<1, 2, 3, 4, 5, 6, 7, 8, 9, 10>>, 3
{<<1, 2, 3>>, <<4, 5, 6, 7, 8, 9, 10>>}
Build an integer from a list of bit positions.
Example
iex> TL.Binary.build_integer_from_bits_list([0,1,3,10])
1035 # = 2^0 + 2^1 + 2^3 + 2^10
Converts the binary representation (of a signed integer) to its decimal representation.
Examples
iex> TL.Binary.decode_signed <<2, 154>>
