Real-World Examples
Example 1
If n = 5, then the number of nonreal complex zeros is:
5 - floor((5 + 1) / 2) = 2
Example 2
If n = 10, then the number of nonreal complex zeros is:
10 - floor((10 + 1) / 2) = 5
Example 3
If n = 15, then the number of nonreal complex zeros is:
15 - floor((15 + 1) / 2) = 7
