On OTP 24:
iex> <<x::float-16>> = <<60, 0>>
iex> x
1.0
iex> <<x::float-16>>
<<60, 0>>
Before OTP 24 we'd get errors or wouldn't match:
iex> <<1.0::float-16>>
** (ArgumentError) argument error while evaluating iex at line 1
<<x::float-16>> = <<60, 0>>
** (MatchError) no match of right hand side value: <<60, 0>>
iex> (fn <<x::float-16>> -> x; _ -> :nomatch end).(<<60, 0>>)
:nomatch
