A somewhat painful triple-nested ternary operator

Question

I went looking through Raphael.js\'s source code to find out how he converted RGB values to HSB. I found out the function he did it in and I was in the process

Answer 1

Yes, it's right (apart from capitalisation differences). Yet, it may be cleaner written without any parentheses, readable as elseif:

if (C == 0)
    h = null;
else if (V == r)
    h = (g - b) / C;
else if (V == g)
    h = (b - r) / C + 2;
else
    h = (r - g) / C + 4;
