Languages with strong typing typically do little implicit conversion and discourage the reinterpretation of representations, while languages with weak typing perform many implicit conversions between data types. In general, both primitive and compound data types can be converted.Įach programming language has its own rules on how types can be converted. Two important aspects of a type conversion are whether it happens implicitly (automatically) or explicitly, and whether the underlying data representation is converted from one representation into another, or a given representation is merely reinterpreted as the representation of another data type. Type conversions can take advantage of certain features of type hierarchies or data representations. An example would be the conversion of an integer value into a floating point value or its textual representation as a string, and vice versa. In computer science, type conversion, type casting, type coercion, and type juggling are different ways of changing an expression from one data type to another.
