Calculate Exponent Without Using thepow()Function in C++ Before we go on to the alternatives of using thepow()function, let us first see how thepow()function works in C++. thepow()Function in C++ As the name says, thepow()orpowerfunction calculates a number’s power. This function takes...
Syntax of pow() function: pow(x, y); Parameter(s) x, y– are the numbers to calculatex^y. Return value double– it returns double value that is calculate result ofxto the power ofy. Sample Input and Output Input: float x = 2; float y = 3; Function call: pow(x,y); Output:...
In thisC++ Tutorial, we learned the syntax of C++ pow(), and how to use this function to find the value of a number raised to a power, with the help of examples.
In C++,pow(a, b) = ab. Example #include<iostream>#include<cmath>usingnamespacestd;intmain(){ // computes 5 raised to the power 3cout<<pow(5,3); return0; }// Output: 125 pow() Syntax The syntax of thepow()function is: pow(doublebase,doubleexponent); pow() Parameters Thepow()...

In a C program, unless you're using the <tgmath.h> macro to call this function, pow always takes two double values and returns a double value.If you use the pow macro from <tgmath.h>, the type of the argument determines which version of the function is selected. See Type-generic ...
