# Elixir: Anonymous Function

## Including the ‘&’ capture operator

In the *interactive Elixir shell* below, an **anonymous function** is demonstrated:

iex(1)> fv = fn(distance) -> :math.sqrt(2 * 9.8 * distance) end

#Function<6.50752066/1 in :erl_eval.expr/5>

iex(2)> fv.(20)

19.79898987322333

In addition to the conventional anonymous function, the `&`

**capture operator** can be used—as an *alternative*:

iex(1)> fv = &(:math.sqrt(2 * 9.8 * &1))

#Function<6.50752066/1 in :erl_eval.expr/5>

iex(2)> fv.(20)

19.79898987322333

Both anonymous functions return *identical* values.
