You probably don't want to be using C variadics.

Instead try the typed one:

float mean(float[] input...) {
	// you don't want to divide by zero
	if (input.length == 0)
		return 0;

	float temp = 0;
	// floats and double initialize to NaN by default, not zero.
	
	foreach(value; input) {
		temp += value;
	}

	return temp / input.length;
}

"input..." seems nice, where can I get more information about it?

"Typesafe variadic functions"

I include most of the language in this free book:

  http://ddili.org/ders/d.en/index.html

which has an Index Section that I find useful to locate information:

  http://ddili.org/ders/d.en/ix.html

I searched for '...' in that page and was happy that one of the candidates was "..., function parameter" which took me here:


<http://ddili.org/ders/d.en/parameter_flexibility.html#ix_parameter_flexibility....,%20function%20parameter>

Note: I've heard before that the links are broken but it works for me. (I enclosed the link with <> to help with it.)
