FAQs

Why isn't <my favorite function> included in the SE_Predefined_Function?

Simple! We didn't think of it. If you'd like to see it, we'd be happy to consider any change request you might offer.

Notes

Composed of Notes

Expression

 The <Expression> components of a <Function>, if any,
 represent the arguments of the function being represented, so a
 <Function> has <Expression> components if that
 <Function> takes arguments. The <Expression> components
 are ordered so as to unambiguously specify which <Expression>
 is being supplied for each argument of the given <Function>.
 The exact interpretation of each argument is defined by
 the specific function.

Fields Notes

value_type

 The value_type of a <Function> instance returns the type of value
 produced when the <Function> instance is evaluated for its arguments.

function

 For a <Predefined Function> instance, the function field specifies
 the function to be used to determine the value of the expression
 when it is evaluated.
