Let’s first review what a [lexeme](https://craftinginterpreters.com/scanning.html#lexemes-and-tokens) is:

> The lexemes are the raw substrings of the source code.

Then the structure of a [token](https://craftinginterpreters.com/scanning.html#location-information):

```java
class Token {
  final TokenType type;
  final String lexeme;
  final Object literal;

  public String toString() {
    return type + " " + lexeme + " " + literal;
  }
}

```

In the case of “NUMBER `42.40` 42.4”, the lexeme is `"42.40"`. It is just a raw string from the source code, and you don’t need to change it in any way:

Does this make sense?
