they do not - linear interpolation will blend between value A and value B based on the blend value X.

the blend value X decides what percentage of A and B end up in the final result to make up a sum of 100%.

if A is 0 and B is 1 and the blend value is 0.3 it means that 30% of one value and 70% of the other value get combined for the final result. in this case it would be 70% of value A and 30% of value B resulting in a final result of .3.

clamp for the parameter will just limit the UI to not allow you values outside the min-to-max value range.

there is also a clamp node that will limit the values in your calculation to not go outside of the min-to-max value range.

Hi.

I've got fully understood thanks to you.

I really appreciate with your help.

Have a nice day:)
