C pow() function

C pow() function - Compute power

Syntax:

double pow(double x, double y)

The pow() function is used to calculate the value of x to the power of y.

Parameters:

Return value from pow()

• Returns the value 1 if y is 0.
• Returns 0 if x is 0 and y is negative.
• Returns 0 if both x and y are 0, or if x is negative and y is not an integer.

Example: pow() function

The following example shows the usage of pow() function.

#include <math.h>
#include <stdio.h> 
int main(void)
{
   double x, y, z;
 
   x = 2.0;
   y = 4.0;
   z = pow(x,y); 
   printf("%lf to the power of %lf is %lf\n", x, y, z);
   x = 2.2;
   y = 3.2;
   z = pow(x,y); 
   printf("\n%lf to the power of %lf is %lf\n", x, y, z);
}

Output:

2.000000 to the power of 4.000000 is 16.000000

2.200000 to the power of 3.200000 is 12.466731
