Hi there,

It seems that there is a mutual contradiction between tests for stages #HT8 and #LV1. Can you please clarify the gap in my understanding?

Here’s the test that fails:

```auto
[tester::#HT8] [test-3] Running test case: 3
[tester::#HT8] [test-3] Writing contents to ./test.lox:
[tester::#HT8] [test-3] [test.lox] 23 == 20
[tester::#HT8] [test-3] $ ./your_program.sh parse test.lox
[your_program] (== 23 20)
[tester::#HT8] [test-3] 𐄂 (== 23 20)
[tester::#HT8] [test-3] Expected line #1 on stdout to be "(== 23.0 20.0)", got "(== 23 20)"
[tester::#HT8] [test-3] Test failed

```

Here’s the test that passes:

```auto
[tester::#LV1] Running tests for Stage #LV1 (Evaluating Expressions - Literals: Strings & Numbers)

Hi @jainsau, the difference in how integers are represented between the parser and the evaluator is an (arguably inconsistent) design choice made by the author of the Lox language.

Here are the reference tests provided by the author:

- [parse](https://github.com/munificent/craftinginterpreters/blob/01e6f5b8f3e5dfa65674c2f9cf4700d73ab41cf8/test/expressions/parse.lox)
- [evaluate](https://github.com/munificent/craftinginterpreters/blob/01e6f5b8f3e5dfa65674c2f9cf4700d73ab41cf8/test/expressions/evaluate.lox)

Thanks. This is not ideal but your response helps.
