Possibly lossy implicit cast in compound assignment

Reports compound assignments if the type of the right-hand operand is not assignment compatible with the type of the variable.

During such compound assignments, an implicit cast occurs, potentially resulting in lossy conversions.

Example:

  long c = 1;
  c += 1.2;

After the quick-fix is applied:

  long c = 1;
  c += (long) 1.2;
