The benefits of forced type conversion include extended functions, saving memory space, improving efficiency, interface adaptation, heterogeneous data conversion and code simplification. Detailed introduction: 1. Extended functions. Forced type conversion can make the program have wider functions. By converting a certain data type to another data type, you can use features and operations that are not originally available; 2. Save memory space. Some data types may occupy a large memory space, and the actual data range required may be small by converting a larger data type to a smaller data type, and so on.

Coercion is the process of converting one data type to another. Although it may have some risks and problems, there are still situations where casting can be very useful. The following are several benefits of forced type conversion:

1. Extended functions: Forced type conversion can make the program have wider functions. By converting one data type to another, you can use features and operations that are not otherwise available. For example, converting an integer to a floating point number allows you to perform floating point operations such as division and square roots.

2. Save memory space: Sometimes, some data types may occupy a large memory space, but the actual data range required may be very small. Memory space can be saved by converting a larger data type to a smaller data type. For example, converting a long integer to an integer can convert a variable that takes up 8 bytes into a variable that takes up 4 bytes, saving half of the memory space.

3. Improve efficiency: In some cases, using forced type conversion can improve the execution efficiency of the program. Frequent type conversions in a program can result in additional computation and memory usage. By using forced type conversion, these additional overheads can be reduced, thereby improving the running efficiency of the program.

4. Interface adaptation: In object-oriented programming, the implementation of interfaces usually requires data transfer between different classes. Casting can be used to convert the implementation of an interface into a specific class or subclass to suit different needs. This allows for more flexible use of interfaces and improves code scalability and reusability.

5. Heterogeneous data conversion: In some cases, we need to convert different types of data to meet different needs. For example, parse a string to a numeric type, or convert a date object to a string. Through cast, these heterogeneous data can be easily handled and manipulated and processed accordingly.

6. Code simplification: Sometimes, we may need to convert a complex data structure into a simple data type. By doing casts, you can simplify your code logic and make your code clearer and easier to understand. For example, converting a multidimensional array into a one-dimensional array can simplify processing and manipulation.

Although casts have several of the above benefits, overuse and abuse should be avoided. When performing forced type conversion, it is necessary to ensure that the data types are compatible and perform corresponding verification and checks to avoid potential risks and problems. When using cast, please pay attention to the readability and maintainability of the code to ensure the correctness and stability of the program.
