The pow() function takes two arguments (base value and power value) and, returns the power raised to the base number. For example, [Mathematics] x y = pow(x, y) [In programming]
Expressions in C consist of one or more variables/constants An expression contains one or more operators, such as c = a + b - 2;
You need pow(); function from math.h header. syntax. #include <math.h> double pow(double x, double y); float powf(float x, float y); long double powl(long double x, long double y); Here x is base and y is exponent. result is x^y. usage. pow(2,4); result is 2^4 = 16. //this is math notation only // In c ^ is a bitwise operator

There is also a list of math functions available, that allows you to perform mathematical tasks on numbers. To use them, you must include the math.h header file in your program: To find the square root of a number, use the sqrt() function:
The following example code computes the sum of 1+4 (3+3^2+3^3+3^4+...+3^N) series using pow () family of standard math library. double pwr, sum=0; int i, n; printf("\n1+4(3+3^2+3^3+3^4+...+3^N)=?\nEnter N:"); scanf("%d",&n); if (n<=0) { printf("Invalid power N=%d", n); return -1; for (i=0; i<n+1; i++) { errno = 0; feclearexcept(FE_ALL_EXCEPT);
The program below takes two integers from the user (a base number and an exponent) and calculates the power. For example: In the case of 2 3 . 2 is the base number; 3 is the exponent; And, the power is equal to 2*2*2
