when for example you say "1/2^2" do you mean "(1/2)^2" or "1/(2^2)"? cause mathematically those two are very different

in c to raise a number to power you should use a pow function from math.h library (or cmath if it's c++). So you should #include <math.h> and then float sum = 1.0+pow(1.0/2.0, 2)+pow(1.0/3.0, 2) or, instead of using pow you can actually do float sum = 1.0+((1.0/2.0)*(1.0/2.0))+((1.0/3.0)*(1.0/3.0)*(1.0/3.0)) it will actually be calculated faster, then the variant with pow
