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 "Local and Common entities".

Minimum is available in Sirius Mods version 7.3 and later.

Syntax

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

Syntax terms

%number	A numeric variable to contain the subscript number of the item in fltNal, the method FloatNamedArraylist object, that has the minimum value after the argument function has been applied.
fltNal	A FloatNamedArraylist object.
itemFunction	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 fltNal declaration and that returns a numeric or string value. As of Sirius Mods version 7.6, the special identity function, This, is the default itemFunction value for the Maximum and Minimum methods. See "Using the This function as the Maximum parameter".

Usage notes

• If itemFunction returns String or Unicode values, Minimum uses the collating sequence of EBCDIC or Unicode, respectively, to determine which item that has the lowest value.
• If the values returned by itemFunction for two or more FloatNamedArraylist items are equal, minimum, values, Minimum returns the name of that item which is closest to the beginning of the FloatNamedArraylist.
• The Maximum function is the opposite of the Minimum function.
• itemFunction 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
