about Map (Value)

Map (Value) does the following:

Map source minimum to source maximum,
map dest. mininmum to dest. maximum.

All values between source min and source max should be equivalently translated into the destination room.

This node usually solves all hairy issues related to the rule of three or rule of proportion (In german this is also called Dreisatz or Satz mit x) Its typically much more maintainable than a straightforward combination of / (Value) and + (Value) nodes.

MapRangeModes:

The modes are only interesting for input values outside the range source min...source max.

Float: if the source values are outside the source region just put the output outside the destination region.

Wrap:if the input is larger than source max just wrap around and begin with the destination min. output values will always be in dest min...dest max

Mirror: if an input values is bigger than source max, then mirror at this value. output values will always be in dest min...dest max

Clamp: if an input value is smaller than source min then output will be destination min. (...bigger than source max then output will be dest max)
