Integer Promotion RulesPromotion rules help the C compiler in maintaining consistency and avoiding unexpected results. The fundamental principle behind the rules of promotion is to ensure that the expression's
In general, it's easier to understand integer issues in C/C++ if you are familiar with the standard promotion and usual arithmetic rules. Such rules specify what happens when data types of different sizes are used in the samearithmetic expressionand how the conversion among them occurs. Aside...
Effect of Integer Promotion Rules on Saturation Charts that use C as the action language also followANSI®Crules for integer promotion. All arithmetic operations use a data type that has the same word length as the target word size. Therefore, the intermediate data type in a chained arithmet...
Be mindful of C integer promotion rules when doing 16-bit operations. For instance, on 32-bit implementations unsigned 16-bit operands will be promoted to signed 32-bit integers, leading to incorrect results in certain cases. The C programs printed by this program are careful to promote 16-...

Casts also occur in some interesting places. Certain unary operators cause a promotion to a signed int in some cases. A '~', '+', or '-' operator, when applied to any value less than 32 bits will result in a signed int. If the value is 32 bits or larger, the type is unchanged...
But if one can't pay attention to some basic rules in the standard with data types leading to the kind of issue raised here, the question to ask is how can additional language facilities such as an array container in Fortran be utilized reliably, not to forget any number of other ...

- I don't think "autocasting" is a thing in Java. There's autoboxing but that's something different. Given your question, you probably mean automatic promotion and conversion. - The rules for automatic promotion and conversion of integer values are not what you stated. Here are the offi...
