WebNov 17, 2012 · Most trigonometric functions, for example, "repeat" after 2*pi (have a translational symmetry of 2*pi ). (More formally, for example, sin (a) = sin (b) if a = b (mod 2*pi) .) This makes it useless to add or subtract 2*pi to or from numbers you use as arguments to these functions. @MvanGeest There are so many use cases.

WebA little-known feature of C++ is that the cmath library actually provides many mathematical constants that you can make use of in your quantitative finance programs.. To include the mathematical constants, you need to use a #define macro called _USE_MATH_DEFINES and add it before importing the cmath library:. #define _USE_MATH_DEFINES #include … WebPrint the value of PI in C++ #define _USE_MATH_DEFINES #include …
WebJul 26, 2013 · But there is also a different idea of how to this, with C++11 we do have constexpr, so pi could be calculated at compile time: constexpr double const_pi () { return std::atan (1)*4; } Of course this will also work at runtime. Alternatively one can use std::atan2 (0,-1), which saves a multiplication. But this code has one big problem: only GCC ...
