Code inspection: Possible overflow

This inspection reports arithmetic on int values that can overflow. Overflow means the computed value does not fit into the int range.

Example

int itemCount = 50_000; int price = 50_000; int total = itemCount * price;

The multiplication result does not fit into int.

How to fix it

There is no dedicated quick-fix for this inspection. Typical fixes are to use a wider type, validate the input range, or make the overflow behavior explicit.

int itemCount = 50_000; int price = 50_000; long total = (long)itemCount * price;
