See https://en.cppreference.com/w/cpp/numeric/math/pow: ``` C++98 added overloads where exp has type int on top of C [pow()](https://en.cppreference.com/w/c/numeric/math/pow), and the return type of std::pow(float, int) was float. However, the additional overloads introduced in C++11 specify that std::pow(float, int) should return double. [LWG issue 550](https://cplusplus.github.io/LWG/issue550) was raised to target this conflict, and the resolution is to removed the extra int exp overloads. ```
