CExp

#define CExp

(

v

)

Value:

    {       \
    double e = exp(v.x);\
    v.x = e*cos(v.y);   \
    v.y = e*sin(v.y);   \
  }

CI

#define CI

(

v

)

Value:

    {         \
    double tmp = v.x;   \
    v.x = -v.y;         \
    v.y = tmp;          \
  }

)

Value:

    {       \
    CI(v);              \
    struct DoubleVect2 vstar = {-v.x, -v.y};  \
    CExp(v);            \
    CExp(vstar);        \
