Section 28.8 Complex Number Library Header File

The header file for the Complex Number Library needs to contain all of the prototypes of our functions but also constants (such as “E”) as well as the definition of the complex number data type. Here are the contents of the file:

/*
 * complexlib.h
 *
 */

typedef struct {
    float real;
    float imag;
} complex_t;

complex_t complex(float x, float y);
complex_t polar(float R, float phi);
complex_t add_c(complex_t z1, complex_t z2);
complex_t subtract_c(complex_t z1, complex_t z2);
complex_t multiply_c(complex_t z1, complex_t z2);
complex_t divide_c(complex_t z1, complex_t z2);
complex_t c_conjugate(complex_t z);
complex_t exp_c(complex_t z);
complex_t log_c(complex_t z);
complex_t sqrt_c(complex_t z);

float abs_c(complex_t z);
float phase_c(complex_t z);
float real(complex_t z);
float imaginary(complex_t z);

void display_c(complex_t z);
