Inquiry Intrinsic Function (Generic): Returns the largest number in the model representing the same type and kind parameters as the argument.
The result is a scalar of the same type and kind parameters as x. If x is of type integer, the result has the value r q - 1. If x is of type real, the result has the value (1 - b -p)b emax.
Integer parameters r and q are defined in Model for Integer Data; real parameters b, p, and e maxare defined in Model for Real Data.
