Under which condition does the Absolute Action return 0?

The Absolute Action is designed to return the magnitude of a number, disregarding its sign. Therefore, when the input parameter is zero, the Absolotal Action will indeed return 0 because the absolute value of zero is zero.

This means that if the input is exactly zero, the action's purpose of calculating the absolute value means it will not change anything, and thus the output will be zero.

In contrast, for inputs greater than zero, the Absolute Action will return the same number, as it is already positive. For inputs less than zero, the action will return the positive equivalent of that number, ensuring that it always presents a non-negative result. Hence, the only scenario where the Absolute Action returns 0 is precisely when the input parameter is zero.
