+== Why is this an issue?
+
+Mistyped suffixes in numeric literals can lead to incorrect interpretations of the values intended by the developer. This is typically seen as a typo which could impact the functionality of the code. The rule does not however address integers that would not fit within the assumed type or specific valid groupings such as `_127` in decimal and octal numbers.
