- x
- A value used in the calculation where x is raised to the power of y.
- y
- A value used in the calculation where x is raised to the power of y.
Returns
The pow function returns x raised to the power of y. If x is negative and y is not an integer value, the pow function will return a domain error.

pow Example
/* Example using pow by TechOnTheNet.com */
#include <stdio.h>
#include <math.h>
int main(int argc, const char * argv[])
{
/* Define temporary variables */
double value1, value2;
double result;
/* Assign the values we will use for the pow calculation */
value1 = 4;
value2 = 2;
/* Calculate the result of value1 raised to the power of value2 */
result = pow(value1, value2);
/* Display the result of the calculation */
printf("%f raised to the power of %f is %f\n", value1, value2, result);
return 0;
}
When compiled and run, this application will output:
4.000000 raised to the power of 2.000000 is 16.000000
