Not

Reverses the logical value of its argument. 【boolean】is the boolean parameter, meaning your input value must be a logical judgment with only true and false outputs, such as comparing which of two values is greater. When the logical judgment of your parameter is true, the function returns false; When the logical judgment of your parameter is false, the function returns true; For example one: 2>3 outputs false, but after reversal, the function outputs true. For example two: NOT({Age} > 18) after the NOT function reversal, it is equivalent to judging {Age} ≤ 18
