tüübivahetus

Tüübivahetus, also known as type casting or type conversion, is a programming concept that involves changing a value from one data type to another. This process can occur implicitly, meaning the compiler automatically performs the conversion without explicit instructions, or explicitly, where the programmer specifies the desired conversion. Implicit conversions are common when a less restrictive type is assigned to a more restrictive one, such as converting an integer to a floating-point number. Explicit conversions require the programmer to use specific casting operators or functions to ensure the conversion is intended and handled correctly.

The purpose of tüübivahetus is to allow operations between different data types or to fit data into a specific format required by a function or variable. For example, you might need to convert a string representation of a number into an actual numerical type to perform calculations. However, type casting can also lead to data loss or unexpected behavior if not handled with care. Converting a floating-point number to an integer, for instance, will truncate the decimal part. Similarly, converting a value of a larger type to a smaller type might result in overflow if the value exceeds the range of the smaller type. Understanding the nuances of tüübivahetus is crucial for writing robust and predictable code.
