The function type depends on the argument types, as follows:

Argument type Function type

The returned value is equal to argument-1 with the greatest value minus the argument-1 with the least value. The comparisons used to determine the greatest and least values are made according to the rules for simple conditions. For more information, see Conditional expressions.
