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. Some programming languages possess this capability Downcasting is useful when the type of the value referenced by the parent variable is known and often is used when passing a value as a parameter

In the below example, the method objecttostring takes an object parameter which is assumed to be of type string.
Python syntax and semantics a snippet of python code demonstrating binary search the syntax of the python programming language is the set of rules that defines how a python program will be written and interpreted (by both the runtime system and by human readers)
The python language has many similarities to perl, c, and java. In computer science, type punning is a common term for any programming technique that subverts or circumvents the type system of a programming language in order to achieve an effect that would be difficult or impossible to achieve within the bounds of the formal language In c and c++, constructs such as pointer type conversion and union — c++ adds reference type conversion and reinterpret. In computer science, type safety is the extent to which a programming language discourages or prevents type errors
The behaviors classified as type errors by a given programming language are usually those that result from attempts to perform operations on values that are not of the appropriate data type, e.g String functions are used in computer programming languages to manipulate a string or query information about a string (some do both) In computer science, string interning is a method of storing only one copy of each distinct string value, which must be immutable In computing, type introspection is the ability of a program to examine the type or properties of an object at runtime
