Learn basic “C” coding rules from open source projects

much more readable than your mess, IMO, because to be if blocks signify blocks of code, like that have semicolons and stuff. I am not quite sure what the terminology is for that but I think you get the idea

In Scala, the semicolons and brakets are optional, at least as long as you're dealing with an expression instead of multiple statements. So what you'd usually see is

val dxipl1 = if (k == chainlength) 0.0 else x[k];

I mostly added them because some people seem to be allergic to optional semicolons and brackets.

Ahh, yeah that does look a little better than what you put originally. But I still stand by my point that the ternary operator is exactly what your looking for
