Ints

Gleam's Int type represents whole numbers.

There are arithmetic and comparison operators for ints, as well as the equality operator which works on all types.

When running on the Erlang virtual machine ints have no maximum and minimum size. When running on JavaScript runtimes ints are represented using JavaScript's 64 bit floating point numbers.

The gleam/int standard library module contains functions for working with ints.

import gleam/int

pub fn main() {
  // Int arithmetic
  echo 1 + 1
  echo 5 - 1
  echo 5 / 2
  echo 3 * 3
  echo 5 % 2

  // Int comparisons
  echo 2 > 1
  echo 2 < 1
  echo 2 >= 1
  echo 2 <= 1

  // Equality works for any type
  echo 1 == 1
  echo 2 == 1

  // Standard library int functions
  echo int.max(42, 77)
  echo int.clamp(5, 10, 20)
}
