Copy and paste with combine
This math plugin will coppy the last math result to a memory location. You are able to get this value later from this memory location and you can combine or overwrite the current math line with the the stored memory value. This plugin is normaly used if you like to overgive a value from one axis to another to reduce the calculation time. There are 1023 memory locations possible.
If you choose to add or overwrite the current math line with a stored memory value that is bigger than a pre given value you will get a unchanged current math line if this trigger value is not reached and a combined value if the stored value is bigger than the given value. You can use this as a trigger function.
