C pow()

The pow() function defined in the math.h header file. It helps to return the value of the first argument(x) raised to the power of the second argument(y) i.e. xy.


double pow(double x, double y); #where x & y should be in double

 

pow() Parameters:

The pow() function takes a single parameter in double. In this first argument is the base value and the second argument is the power value. Using the cast operator we can explicitly convert the type to double to find the power of type int, float, or long double.

Parameter Description Required / Optional
x base value Required
 y power value  Required 

pow() Return Value

The return value of pow() function is a number in float.

Input Return Value
x & y xis returned

Examples of pow()

Example 1: Working of pow() function in C?


#include <stdio.h>
#include <math.h>
int main()
{
    double B, P, output;

    printf("Enter the base number: ");
    scanf("%lf", &B);

    printf("Enter the power raised: ");
    scanf("%lf",&P);

    output = pow(B,P);

    printf("%.1lf^%.1lf = %.2lf", B, P, output);

    return 0;
}

Output:


Enter the base number: 4.00
Enter the power raised: 2.00
4.00^2.00 = 16.00

Example 2: How pow() function worked in C?


#include <stdio.h>
#include <math.h>
int main () {
   printf("Value 8.0 ^ 3 = %lf\n", pow(8.0, 3));

   printf("Value 3.05 ^ 1.98 = %lf", pow(3.05, 1.98));
   
   return(0);

}

Output:


Value 8.0 ^ 3 = 512.000000
Value 3.05 ^ 1.98 = 9.097324
