The IEEE754 standard specifies how floating point numbers should be represented in binary form, and is the standard adopted by most programming languages.
In elixir, I just discovered today that floating point numbers can be easily converted to this representation.
binary16
iex> <<0.000000059604645::float-16>>
<<0, 1>>binary32
iex> <<0.15625::float-32>>
<<62, 32, 0, 0>>binary64
iex> <<0.01171875::float-64>>
<<63, 136, 0, 0, 0, 0, 0, 0>>
