Lookups allow you to name the function you are creating - with Auxiliary With Lookup the function is embedded in the auxiliary.
to multiply use
lookup name((0,0),(1,1))
lookup output = lokkup name(lookup input)
output = lookup output * other stuff

Hi
The two type of lookups are roughly the same. The constant lookup is a lookup function that needs an argument to generate a value. The auxiliary lookup is a lookup where the argument is already settled in the definition of the auxiliary.
See the simplistic model joined. When you put different values to the constant you will see that the lookup and the auxiliary lookup will give exactly the same results.
