i just came across some code, and i'm trying to understand why the developer
chose to use the pow() function instead of simply multiplying as the 2nd
arguments are always 2. i'm certainly no mathematician, but if the 2nd
argument is going to be 2, why use pow()? is it just a matter of taste?
why use this:
float dist = pow(red - r, 2) + pow(green - g, 2) + pow(blue - b, 2);
instead of:
float dist = ((red - r) * 2) + ((green - g) * 2) + ((blue - b) * 2);
