Hello!

How do I use the math constant Pi in my CCS code? I included the math.h header file. I used the identifier 'PI'.

However, the compiler gives the error that the identifier is undefined.

Thank You

Hello,

math.h defines:

#define M_PI 3.14159265358979323846 /* pi */
#define M_PI_2 1.57079632679489661923 /* pi/2 */
#define M_PI_4 0.78539816339744830962 /* pi/4 */
#define M_1_PI 0.31830988618379067154 /* 1/pi */
#define M_2_PI 0.63661977236758134308 /* 2/pi */
#define M_2_SQRTPI 1.12837916709551257390 /* 2/sqrt(pi) */
