You can calculate one number raised to the power of another, such as x using the function ans = pow(x, y). To use this function, you need to use another header file, math.h. Example: Calculate 2 to the 3rd power Calculate 1.3 to the 2nd power Edit the same program but declare the variables as floating-point values. You can calculate the square root of a number using the function call Z = sqrt(x). The sqrt() function is also defined in the math.h header file. The data type of the result of this calculation is double.
