i just came across some code, and i'm trying to understand why the
chose to use the pow() function instead of simply multiplying as the
arguments are always 2. i'm certainly no mathematician, but if the
argument is going to be 2, why use pow()? is it just a matter of
Those two lines mean entirely different things. x * 2 != x ^ 2.
Consider x = 3. 3 * 2 = 6. 3 ^ 2 = 9.
If the author didn't want to use the pow function, he/she might
streamline by doing x * x, but it's possible the author just didn't
want to have to write all that out, and felt that using the pow
function was more immediately clear what was going on without having
to write or read much.
