Raises a complex number to a complex power #include <complex.h> double complex cpow ( double complex x , double complex y ); float complex cpowf ( float complex x , float complex y ); long double complex cpowl ( long double complex x , long double complex y ); The cpow( ) function raises its first complex argument x to the power of the second argument, y. In other words, it returns the value of xy. The cpow( ) function has a branch cut along the negative real axis to yield a unique result. Exampledouble complex z = 0.0 + 2.7 * I; double complex w = 2.7 + 0.0 * I; double complex c = cpow(w, z); // Raise e to the power of i*2.7 printf("%.2f %+.2f \xD7 I raised to the power of %.2f %+.2f \xD7 I " "is %.2f %+.2f \xD7 I.\n", creal(w), cimag(w), creal(z), cimag(z), creal(c), cimag(c)); This code produces the following output: 2.70 +0.00 x I raised to the power of 0.00 +2.70 x I is -0.90 +0.44 x I.
