How to convert a Data List to specific value?

Hello everybody,

I have a proble with Data Management. I try to convert my Parameter List to specific Values. I have a list of parameters where the values are betwenn "0" and "1" so I want to seperate the values and get only 7 different values. For example this schould be like this:

The values between 0 and 0.5 will converted to 0.4 while the values betwenn 0.5 and 1 will converted to 0.8

Mathematical Discription:

if 0.0 < x < 0.5 than "0.4"

if 0.5 < x < 1.0 than "0.8"

I try to solve it with boleans (Or, And, Xor, Ternary etc. Gates) but not succes. Is there a possibility to solve it with Funktions? Or have any body for me a clue hove to convert datas tu specific values.

Thanks,

ILIAS

Because you only have values between 0 and 1 if you converted them into integers you would have zeros for all values less than 0.5 and ones for those greater. This forms a pattern from which you can weave your intended values into a list. See Image below.

Alternatively you could try something like this: http://www.grasshopper3d.com/forum/topics/replace-null-items-in-a-l...

Hi Ilias

you can also use a c# component in GH07 with x as List of double



if(x.Contains(double.NaN))

return;



List num = new List();



for(int i = 0; i < x.Count;i++)

{

if(x[i] > 0 && x[i] < 0.5)

num.Add(0.4);

else

num.Add(0.8);

}



A = num;
