WebC++ has a predefined constant in its math library which we can use to access the value of pi wherever needed in our program. We use the following header file : #define _USE_MATH_DEFINES #include Here, _USE_MATH_DEFINES is a #define macro. Later in the program, we use M_PI to access the value of PI. 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).
