C++ log2() function: Here, we are going to learn about the log2() function with example of cmath header in C++ programming language.
If x is an integer, this function essentially returns the zero-based index of the most significant 1 bit of x.By default, this function's global state is scoped to the application. To change this behavior, see Global state in the CRT....
