Minimum (FloatNamedArraylist function)

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

This function returns the number (subscript) of the FloatNamedArraylist item that has the minimum value after the application of a specified function to each item. The function that gets applied to each FloatNamedArraylist 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

%number = fltNal:Minimum[( [itemFunction])]

Syntax terms

%num	A numeric variable to contain the subscript number of the item in the indicated FloatNamedArraylist that has the minimum value after the argument function has been applied.
%fnamrayl	A FloatNamedArraylist 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 %fnamrayl 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 Maximum and Minimum 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 FloatNamedArraylist items have equal, minimum, values, Minimum returns the subscript of the item that appears closest to the beginning of the FloatNamedArraylist.
• 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 Maximum or Minimum for an Arraylist.

Examples

The following request finds the minimum and maximum differences between the two values that constitute each item in the FloatNamedArraylist. A class method is the Minimum and Maximum function parameter.

For more examples of Minimum and Maximum for collections, see Finding collection maxima and minima, and sorting.

b class annual public

variable ybegin is float variable yend is float constructor newa (%beg is float, %end is float) function myprint is string len 24 function chg is float

end public

constructor newa (%beg is float, %end is float)

%ybegin = %beg %yend = %end

end constructor

function myprint is string len 24

return 'ybegin=' with %ybegin with ', ' - with 'yend=' with %yend

end function

function chg is float

%chg is float %chg = %yend - %ybegin return %chg

end function

End class

%fann is floatnamedArraylist of object annual %fann = new %fann(12) = newa(621, 650) %fann(14) = newa(334, 343) %fann(15) = newa(288, 276) %fann(13) = newa(141, 182) %fann(11) = newa(131, 115)

%i is float for %i from 1 to %fann:count

print %fann:namebynumber(%i) With ': ' - With %fann:itembynumber(%i):myprint

end for

print 'item ' %fann:minimum(chg) ' has the minimum increase' print 'item ' %fann:maximum(chg) ' has the maximum increase'

end

The result is.

11: ybegin=131, yend=115 12: ybegin=621, yend=650 13: ybegin=141, yend=182 14: ybegin=334, yend=343 15: ybegin=288, yend=276 item 11 has the minimum increase item 13 has the maximum increase
