sqrt ( ) function for complex number in C++
Given is the task to find the working of sqrt() function for complex number. Basically the sqrt( ) is a function present in complex header file. This function is used to calculate the square root of complex number.
Syntax
template<class t> complex<t> Sqrt(const complex<t>& x);
Parameter
x − This parameter x which represent the complex number.
Return Value
This function returns the square root of the complex number.
Input − Sqrt(3,8i)
Output − (2.4024,1.6649)
Input Sqrt(7,1i)
Output − (2.6524,0.1885)
Example
#include<iostream.h>
#include<complex.h>
Using namespace std;
int main( ){
/ / Defining of complex Number
Complex<double> x(4,9);
Cout<< “ The square root of “ << x << “ = “ << sqrt(x) << endl;
Return 0;
}Output
If we run the above code it will generate the following output
The square root of (4,9) = (2.631,1.710)
Example
#include<iostream.h>
#include<complex.h>
Using namespace std;
int main( ){
/ / defining the complex Number
Complex<double> x(2, 6);
Cout<< “ The square root of “ << x << “ = “ << sqrt(x) << endl;
return 0;
}Output
If we run the above code it will generate the following output
The square root of (2,6) = (2.0401,1.4704)
