FAQ
How do I define Pi in C++?
You can define Pi in C++ using the constant M_PI from the 'cmath' library. For example: #include <cmath> const double pi = M_PI;
What is the difference between 'cmath' and 'math.h'?
'cmath' is the C++ version of the C library 'math.h'. Both provide mathematical functions, but 'cmath' includes them in the std namespace.
Can I calculate Pi manually in C++?
Yes, you can calculate Pi manually using various algorithms such as the Leibniz formula, but using predefined constants like M_PI is recommended for simplicity and accuracy.
