[FT3] Global Math Tool - Temp, Rainfall, *, and /
In the Global Math Tool, Temperature and Rainfall seem to be 'immune' to multiplication and division. More precisely, an operation such as
Temperature = Temperature * Constant
seems to always act as if the Constant is 1, regardless of the value specified. Similarly for division. And Rainfall seems to act the same way.
Is this supposed to work? If so, is it obvious what I might be doing wrong?
FWIW, the effect I was trying to get was to 'blend' temperatures in an area toward a constant value, that is, calculate the new temperature as a weighted average of the old temperature and a constant.
T(new) = T(old)*w1 + c*w2, where w1+w2 = 1
Although now as I write this, it occurs to me that there might be a way to use a partial selection to accomplish this. Nevertheless, the Global Math Tool would be a bit more convenient if there is a way to make that work.
