NUM12-EX0: Java's narrowing conversions are both well defined and portable. The effects of narrowing on integral types can be easily reproduced in code; however, the effects of narrowing on floating-point types and between floating-point types and integral types cannot be easily represented. Knowledgeable programmers may intentionally apply narrowing conversions involving floating-point types in contexts where their output is both expected and reasonable. Consequently, narrowing conversions are permitted when the code contains comments that document both the use of narrowing conversions and the anticipated truncation. A suitable comment might read:
// Deliberate narrowing cast of i; possible truncation OK
