i need to understand how the map range node works.
@hideki turns numbers from one range in to values in a different range doesn't it? like linear interpolation

@icedquinn yeah but i don't understand how it works, has two values "from" and two valuest "to"
@hideki 
well 32-212 to 0-100 but still.
well 32-212 to 0-100 but still.
then it takes that 0.5 and puts it on the new scale 0-100. so the half point of that is 50.
thus it (naively) maps farenheit to celsius
