Thank you.

Read about creation of custom user function(s).
So, to bring upper equation to AB function it is as simple as this:

function Normalization(x, x_min, x_max) {	
	z = (x - x_min) / (x_max - x_min + 1e-9);
	return z;
}

E.g. x_min may be LLV and x_max be HHV().

So e.g.

x_min = LLV(C,100);
x_max = HHV(C,100);
z = Normalization(C, x_min, x_max);

As aside lately there has been implemented a function named Remap() in AB 6.30.

Remap( value, srcMin, srcMax, dstMin, dstMax )

Mathematically the function performs the following linear transformation:
result = (value - srcMin) * (dstMax - dstMin) / (srcMax - srcMin) + dstMin;

Remap() function is official way to do normalization.
