Logarithm on Attributes
Hi!
I wanted to obtain logarithm on my attributes. I used the operator logarithm. I was missing the ability of the operator to handle 0 values within attributes. That's a problem for the logarithm function. I thought it might could handle this but I am not sure if the operator can?
Maybe I have to use than a macro right to type in this formula: log(x + 1) because with this formula it could handle 0.

i know it's not mathematically correct, but i think the operator follows IEEE 754 and does return Infinity for +/0.
But anything below will be converted into a missing value.
