The cpowf
function is a C library function that raises a complex number to a complex power.
The following illustration shows the functionality of the cpowf
function:
To use the cpowf
function, we need to include the complex.h
header file, as shown below:
#include <complex.h>
The cpowf
function takes two arguments and returns the complex power. It is declared as follows:
The cpowf
function takes two arguments of the float complex
type.
The first parameter is the number we want to raise
The second parameter is the power with which we want to raise the number
The cpowf
function computes and returns the power in the float complex
type.
The code below shows the use of cpowf
function in C:
#include <stdio.h>#include <complex.h>int main() {//Declare x and yfloat complex x = 1.0+2.0*I;float complex y = 3.0;//Call cpowf i.e x^yfloat complex ans = cpowf(x,y);//Display resultprintf ("(1+2i)^3 = %f%+fi\n", creal(ans), cimag(ans) );return 0;}
