// An @int node is any literal integer in Ruby. They can come in a number of
// bases, and look like the following:
//
// Binary (2) - 0b0110
// Octal (8) - 0o34 or 034
// Decimal (10) - a normal number like 159
// Hexidecimal (16) - 0xac5
//
// If it's a decimal number, it can be optional separated by any number of
// arbitrarily places underscores. This can be useful for dollars and cents
// (34_99), dates (2020_11_30), and normal 3 digit separation (1_222_333).
function printInt(path, _opts, _print) {
const { body } = path.getValue();
// If the number is a base 10 number, is sufficiently large, and is not
// already formatted with underscores, then add them in in between the
// numbers every three characters starting from the right.
if (!body.startsWith("0") && body.length >= 5 && !body.includes("_")) {
return ` ${body}`
.slice((body.length + 2) % 3)
