Why pow(10,5) = 9,999 in C++

Question

Recently i write a block of code:

const int sections = 10;

for(int t= 0; t < 5; t++){
   int i = pow(sections, 5- t -1);  
   cout << i << en         


        

Answer 1

You're assigning the result to an int. That coerces it, truncating the number.

This should work fine:

for(int t= 0; t < 5; t++){
   double i = pow(sections, 5- t -1);  
   cout << i << endl;
}
