Question

I want to ask, in one of my c++ programming question, there ask me to find error of computation and the error of computation is defined to be | Computed value - Exact value|. I already write the program and the output of the error of computation is negative, how can i write in the program so that the output of the error of computation will become positive??

Answer 1

Look into the math library and the absolute value function.

Answer 2

#include <cmath>

int main() {
//your code goes here ....
std::cout << std::abs(-4.156);
}
