 # Change Variable Based On Range

#1

I want to change a variable based on an input and a possible range. Similar to how rainbowValue sets a color but based on numbers,

For example. If the temperature is between 70 and 80 set the variable to a number between 0 and 100.
RainbowValue(Temp, 70, ’0’, 80, ’100’)

71 would return a value of 10
72 would return a value of 20

I can create a simple piston to figure out this example but I’m wondering if there’s an expression that’ll do it for me.

#2

For your example, it is a simple equation:

output=((input-minInput)/(maxInput-minInput))*(maxOutput-minOutput)

I out together a simple piston to demonstrate:

Which produces:
