I program in Java, C and Python.

The rule for automatic coercions among arithmetic types have been augmented to handle the richer set of types

Source: "The C Programming Language"

But what does "coercion" mean? The answers say it's like type conversion and implicit casts and implicit type conversions and called autoboxing where I read it. So what is the difference between automboxing and coercion?

Thanks

Coercion is another name for an implicit type cast, i.e. one mandated by the language rules, and not explicitly added by the programmer.
