Name of item with minimum value or minimum value of function applied to items (NamedArraylist class)


This function returns the name (subscript) of the NamedArraylist item that has the minimum value after the application of a specified function to each item. The function that gets applied to each NamedArraylist item, which you identify in the argument to Minimum, must be a method that operates on the item type and returns a User Language intrinsic datatype (Float, String, Longstring, or Unicode) value.

The system intrinsic classes are discussed in "Intrinsic classes". Local methods are discussed in ?? refid=localm..

Minimum is available in Sirius Mods version 7.3 and later.

Syntax

%string = nal:Minimum[( [itemFunction])]

Syntax terms

%str A string variable to contain the subscript name of the item in the indicated NamedArraylist that has the minimum value after the argument function has been applied.
%namrayl A NamedArraylist object.
function A method value (a method name literal, a method variable, or even a method that returns a method value) for a method that operates on objects of the type specified on the %narrayl declaration and that returns a numeric or string value.

As of Sirius Mods version 7.6, the special identity function, This, is the default function value for the Minimum and Maximum methods. See "Using the This function as the Maximum parameter".

Usage notes

  • If the function applied by Minimum returns string values, Minimum uses the decimal-equivalent value of the character bytes and determines the number of the item that has the lowest value. Therefore, lowercase letters are ranked alphabetically and the minimum lowercase letter is "a"; the uppercase letters are ranked alphabetically and the minimum uppercase letter is "A"; "z" ranks lower than all the uppercase letters; and all letters rank lower than any number.
  • If one or more NamedArraylist items have equal, minimum, values, Minimum returns the name of the item that appears closest to the beginning of the NamedArraylist.
  • The Maximum function is the opposite of the Minimum function.
  • The parameter for Minimum is a method value, not a User Language expression. That is, you cannot provide a function that itself has an argument (say, ToIntegerPower(2)) as the Minimum parameter. Example "Maximum/Minimum with local method" shows a way to apply ToIntegerPower with the Maximum or Minimum method for an Arraylist.
  • For an example of the Minimum method for a NamedArraylist, see NamedArraylist Maximum function example, and also see [[Collections#Finding collection maxima and minima, and sorting|Finding collection maxima and m
