For context, I am a programmer, not a mathematician, so please forgive my math-ignorance.

I am implementing this calculation in an application that I am working on, but at the bottom of the page, I came across something I have not seen before.

Towards the end of the equation in points (26, 27 & 28) 3 items are individually defined as equaling 1 default. Is there any special meaning here? or can I just set their value to be 1?

Thanks!

    The "syntax" depends on the programming language used, but - in general - default : "refers to the preexisting value of a user-configurable setting that is assigned to a software application, computer program or device." – Mauro ALLEGRANZA Sep 05 '18 at 09:52
  • I think the meaning of "default" is that $K_L, K_C, K_H$ usually take the value $1$, but may be given values other than $1$ if a slightly different model for $\Delta E$ is required. If you are implementing the $\Delta E$ calculation as a function you could make $K_L, K_C, K_H$ optional parameters which all default to a value of $1$ unless the user specifies some other value. – gandalf61 Sep 05 '18 at 10:05

Thanks,

I took a peek at the javascript implementation for the calculator on the same site.

it turns out to be just as straight forward as it looks:

var kL = 1.0;
var kC = 1.0;
var kH = 1.0;
