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

Answer 1

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

Answer 2

Coercion refers to "type coercion". In other words, you add a variable of type Integer to a Float, the Integer will be coerced to Float, and the numbers added together.

Answer 3

Coercion is the process of changing one data type into another. http://en.wikipedia.org/wiki/Type_conversion
