C++ Math cbrt()

This function is used to find the cube root of a given number.

Consider a argument 'arg' :

Syntax

Syntax would be :

double cbrt(double arg);
float cbrt(float arg);
long double cbrt(long double arg);
double cbrt(integral arg);

Parameter

arg : It is the value of float or integer type.

Return value

It returns the cube root of a given number arg.

Example 1

Let's see a simple example when argument 'arg' is of integer type

#include <iostream>
#include<cmath>
using namespace std;
int main()
{ int arg=8;
 std::cout << "Cube root of a number is :" <<cbrt(arg);
  return 0;
}

Output:

Cube root of a number is :2

Example 2

Let's see a simple example when an argument 'arg' is of float type.

#include <iostream>
#include<cmath>
using namespace std;
int main()
{
 float arg=12.8;
 std::cout << "Cube root of a number is :" <<cbrt(arg);
  return 0;
}

Output:

Cube root of a number is :2.33921
