Repro Code

enum Test {
  // Spicy numbers – no errors
  MinusZero = -0,
  MinusZero2 = -0,
  MinusOne = -1,
  MinusOne2 = -1,
  PlusOne = +1,
  PlusOne2 = +1,
  PlusZero = +0,
  PlusZero2 = +0,

  // Vanilla numbers – yes errors
  BoringNumber = 1,
  BoringNumber2 = 1,
}

ESLint Config

module.exports = {
  parser: "@typescript-eslint/parser",
  rules: {
    "@typescript-eslint/no-duplicate-enum-values": "error"
  },
};

tsconfig

{
  "compilerOptions": {
    // ...
  }
}

Expected Result

• +Something numbers should be considered equal to their unsigned counterparts. E.g. +1 = 1.
• Minus numbers should be checked against other minus numbers.
• -0 and 0/+0 should be considered to be different values, because math.

Actual Result

Rule doesn't lint numbers if they have + or - in front of them.
