# Power calculation in java without using pow function

## How to calculate a power value of a given number

The logic is something--

2. Check out how much is the power to be calculated

3. multiply the given number in 1 for these many times (given in step-2)

Say i have a number called 2 (getting in logic no-1)

i need to calculate the 2 to the power 4 value(getting 4 at logic no-2)

So output of that is 2*2*2*2=16

## Let us implement that in code.

public void calcpow(int val,int powr) {

//this function takes two input ...the number and the power value

int res=1;

//res is the integer type temp variable This is initialized to 1 to handle the condition where power=0. x to the power 0=1

for(int i=1;i<=powr;i++) {

res=res*val;

}

System.out.println(res);

}
