Integers floats and atoms

Learn Integers floats and atoms in Elixir through a focused explanation, a dedicated topic-specific example, an engineering boundary, and a mastery check.

10 min read • Beginner

Integers floats and atoms is a focused Elixir lesson inside Values and Matching. The example uses the construct named in the lesson directly rather than reusing a generic placeholder.

Trace the example from its inputs through Integers floats and atoms and identify the behavior that would change if that construct were removed or replaced. Pay attention to the language-specific rules shown by the syntax, because neighboring lessons intentionally exercise different mechanisms.

Topic-specific example

elixir-0001-e2c9a841ac.exs
elixir Try It Live 
values = [2, 3, 4]
IO.inspect(Enum.sum(values)) # Integers floats and atoms
Edge case / engineering note

For Integers floats and atoms, test one realistic boundary: empty data, invalid input, unavailable resources, lifetime/cleanup, type constraints, or concurrency timing where applicable. A successful happy path is not enough to prove the construct is used correctly.
