WebThe standard library specializes mathematical constant variable templates for all floating-point types (i.e. float, double and long double ). A program may partially or explicitly specialize a mathematical constant variable template provided that the specialization depends on a program-defined type. Feature-test macro. In order to do that, one should define _USE_MATH_DEFINES before including the header. The following solution works correctly: #define _USE_MATH_DEFINES and then #include < math.h > However, I would like to add the definition of _USE_MATH_DEFINES to the Preprocessor Definitions (Project->Properties->C/C++->Preprocessor->Preprocessor Definitions).
