Name of item with maximum value or maximum value of function applied to items (FloatNamedArraylist class)
Maximum returns the (numeric) name of that item of the FloatNamedArraylist item with the maximum numeric value as returned by a specified function. The function applied to each FloatNamedArraylist item, which you specify with the required itemFunction argument, must be a method that operates on the item type and returns a User Language intrinsic datatype (Float, String, or Unicode) value.
Syntax
%number = fltNal:Maximum[( [itemFunction])]
Syntax terms
| %number | A numeric variable to contain the name of the item in the indicated FloatNamedArraylist that has the maximum value as returned by the argument function. |
|---|---|
| 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 an intrinsic 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" for more information. |
Usage notes
- If the function applied by Maximum returns string values, Maximum uses the decimal-equivalent value of the character bytes and determines the number of the item that has the greatest value. Lowercase letters are first ranked alphabetically; then uppercase letters, also ranked alphabetically; finally followed by the numbers; that is:
'a'..'z','A'..'Z',0..9. - If the values returned by itemFunction for two or more FloatNamedArraylist items are equal, maximum, values, Maximum returns the (numeric) name of that item which is closest to the beginning of the FloatNamedArraylist.
- The parameter for Maximum 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 Maximum parameter. The "Maximum and Minimum with local method" example shows a way to apply ToIntegerPower with Maximum.
- Maximum is available in Sirius Mods Version 7.3 and later.
Examples
For examples of Maximum (and Minimum) calls, see the "FloatNamedArraylist Minimum function example" in the Minimum method description, and "Finding collection maxima and minima, and sorting".

- Minimum is the opposite of the Maximum function.
