@NAND

The NAND function takes one or more Boolean parameters and evaluates each until the first true value is found or until all parameters have been evaluated. If a true parameter value is found, the function returns false. It will return true if all parameters evaluate to false. The function will end evaluation when the first true value is found.

Parameters

    @NAND (Expression 1 [, ..., Expression N])
  • Expression 1 Required Boolean parameter, evaluated by the function for its Boolean value. If false, the function will return true. If true, the function will continue to evaluate the next parameter.
  • Expression N Optional Boolean parameter, evaluated by the function for its Boolean value. If false, the function will return true. If true, the function will continue to evaluate the next parameter, or if no more parameters are provided, the function will return false.

Supported Return Types

Boolean
