What is cpowl() in C?
The cpowl function is a C library function that raises a complex number to a complex power.
The following illustration shows the functionality of the cpowl function:
To use the cpowl function, we need to include the complex.h header file, as shown below:
#include <complex.h>
Syntax
The cpowl function takes two arguments and returns the complex power. It is declared as follows:
Parameters
The cpowl function takes two arguments of the long double 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.
Return Value
The cpowl function computes and returns the power in the long double complex type.
Example
The code below shows the use of cpowl function in C:
#include <stdio.h>#include <complex.h>int main() {//Declare x and ylong double complex x = -1.5 + I*1.5;long double complex y = 3.0;//Call cpowl i.e x^ylong double complex ans = cpowl (x,y);//Display the resultprintf ("(1+2i)^3 = %f%+fi\n", creal(ans), cimag(ans) );return 0;}
