The function NotEmptyNumeric () checks whether a variable contains a numeric value, no or an invalid value. If the value of the variable is invalid, an empty string is returned as the result. This prevents further processing within a Ruleset. The RuleSet is simply skipped without an error being triggered. | It is also possible to specify a second argument within the function to specify the zero value with which the value in the first argument is to be compared. If both values are identical, the function also returns an empty string.
