abs() function for complex number in c++
The abs() function for complex number is defined in the complex header file. This function is used to return the absolute value of the complex number z.
Syntax:
template<class T> T abs (const complex<T>& z);
Parameter:
- z: It represents the given complex number.
Return: It returns the absolute value of the complex number.
Below programs illustrate the above function:-
Example 1:-
#include <bits/stdc++.h>
using namespace std;
int main ()
{
complex< double > complexnumber (5.0, 12.0);
cout << "The absolute value of " << complexnumber << " is: " ;
cout << abs (complexnumber) << endl;
return 0;
}
|
Output:
The absolute value of (5,12) is: 13
Example 2:-
#include <bits/stdc++.h>
using namespace std;
int main ()
{
complex< double > complexnumber (4.0, 3.0);
cout << "The absolute value of " << complexnumber << " is: " ;
cout << abs (complexnumber) << endl;
return 0;
}
|
Output:
The absolute value of (4,3) is: 5
