Class IntegerLiteral

An integer literal. For example, 23.

An integer literal can never be negative except when:

  • It is written in binary, octal or hexadecimal notation
  • It is written in decimal notation, has the value 2147483648 and is preceded by a minus; in this case the value of the IntegerLiteral is -2147483648 and the preceding minus will not be modeled as MinusExpr.

In all other cases the preceding minus, if any, will be modeled as a separate MinusExpr.

The last exception is necessary because 2147483648 on its own would not be a valid integer literal (and could also not be parsed as CodeQL int).
