Variable-Type Intrinsic Functions

The type of some intrinsic functions depends on the type(s) of its arguments.

Argument Types

Table 14-6 lists the types of arguments that intrinsic functions can have, tells you what

you must specify for an argument of each type, and tells you what is used in

determining the function’s value.

Table 14-4. Variable-Type Intrinsic Functions

Function Name Value Returned

MAX Function

Value of maximum argument

MIN Function

Value of minimum argument

RANGE Function

Value of maximum argument minus value of minimum

argument

SUM Function

Sum of arguments

Note. Not every function in Ta bl e 1 4- 4

can have arguments of every type in Table 14-5. For

valid argument types for a particular function, see the description of that function later in this

section.
