Explicit conversion, also known as type casting, is a programming technique used to convert a variable from one data type to another. This process is intentional and requires the programmer to specify the desired type, ensuring that the conversion is clear and controlled. For example, converting an integer to a floating-point number allows for more precise calculations. In many programming languages, explicit conversion is performed using specific functions or syntax. For instance, in Python, you might use the `float()` function to convert an integer to a float. This method helps prevent errors that could arise from automatic conversions, providing greater control over data handling.
