Look into base types

So nothing special here

There are bunch of data types:

• floats

Numbers with a floating point

1.1
1.2

• ints

300_000
1

OCaml as ruby, elixir does, allow you to place underscores in the middle of numeric literals to improve readability. Note that underscores can be placed anywhere within a number, not just every three digits.

• booleans

(1 < 2) = false;;

• chars

"a";;

• strings (immutable)

"Hello";;
