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); _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
