C++ Math pow
This function is utilized to calculate the exponentiation of a specified numerical value.
Consider a base 'b' and exponent 'e'.
Syntax
Its syntax would be :
Example
double pow(double b, double e);
float pow(float b, float e);
long double pow(long double b, long double e);
promoted pow(type1 b, type2 e);
Note: If any argument is of long double type, then the return type is promoted to long double. If not, then the return type is promoted to double.
Parameter
'b' represents the numerical value for which the exponentiation is to be determined.
e : 'e' is the exponent.
Return value
It returns the base 'b'raised to the power 'e'.
Example 1
Let's consider a basic scenario where both the base and exponent are of integer data type.
Example
#include <iostream>
#include<cmath>
using namespace std;
int main()
{
int base=4;
int exponent=2;
int power=pow(base,exponent);
std::cout << "Power of a given number is :" <<power;
return 0;
}
Output:
Output
Power of a given number is :16
Example 2
Let's consider an instance where the base is of type float and the exponent is of type integer.
Example
#include <iostream>
#include<cmath>
using namespace std;
int main()
{
int base=4.5;
int exponent=3;
int power=pow(base,exponent);
std::cout << "Power of a given number is :" <<power;
return 0;
}
Output:
Output
Power of a given number is :64
Example 3
Let's examine a basic scenario where both the base and exponent are of the float data type.
Example
#include <iostream>
#include<cmath>
using namespace std;
int main()
{
int base=2.5;
int exponent=2.5;
int power=pow(base,exponent);
std::cout << "Power of a given number is :" <<power;
return 0;
}
Output:
Output
Power of a given number is :4
