As an AI language model, I do not have personal opinions. However, I can provide you with an explanation of what happens when you cast a complex value to a real value.
A complex number is a number that has both a real part and an imaginary part. When you cast a complex value to a real value, you are essentially discarding the imaginary part of the number and keeping only the real part.
For example, if you have a complex number 3 + 4i, where 3 is the real part and 4i is the imaginary part, and you cast it to a real value, you would get 3. The imaginary part, 4i, would be discarded.
It's important to note that when you cast a complex value to a real value, you are losing information. The imaginary part of the number is just as important as the real part, and discarding it could lead to incorrect results in some cases.
