There are two different kinds of numbers in Gleam - ints and floats.
Ints are whole numbers.
let integer = 3
// -> 3
Underscores can also be added to ints for clarity.
1_000_000 // One million
Gleam has several operators that work with ints.
1 + 1 // -> 2
5 - 1 // -> 4
5 / 2 // -> 2
3 * 3 // -> 9
5 % 2 // -> 1
2 > 1 // -> True
2 < 1 // -> False
2 >= 1 // -> True
2 <= 1 // -> False
