WebMar 24, 2024 · C++98 added overloads where exp has type int on top of C 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 was raised to target this conflict, and the resolution is to removed the extra int exp overloads. WebI recently implemented tan, cot, atan, atan2 using SSE2 intrinsics, which serve as extensions to the SSE2 implementations of sin, cos, exp, log by Julien Pommier. WIP because the original library also implements SSE1 + MMX, which mine don't. I may or may not add them in later, I couldn't get MSVC to compile MMX intrinsics.
