### [Function] Min/Max including with Associative Arrays

Posted:

**04 Dec 2017, 14:46**[Function] Min / Max

I have had a Min/Max function in my library for years that used a variadic parameter so that you could pass it as many parameters as you liked. This allowed it to also work with a simple array parameter if followed by a * but I discovered today that it did not work for associative arrays so I made a small tweak.

The Min function requires Unicode encoding of the file as it uses a special extended character.

If that is a problem this ANSI encoding function can be used.This uses the _NewEnum().Next to get the starting value for comparison in an associative array which makes this function slower than the one above.

Examples of usage:Important to realize that alpha characters are greater than numbers.

Even thought Min/Max functions are fairly simple I figured these were worth posting as the ability to find the Min or Max value in an array is a pretty common need. These are also the fastest functions I could find that handled all the cases these functions can handle.

There can be 1 or more parameters that can be literals, variables, simple arrays, or associative arrays.

Code: Select all

```
Min(X:="�", List*) ; X := chr(0xffff)
{
for key, element in List
if (element < X)
X := element
return X
}
Max(X:="", List*)
{
for key, element in List
if (element > X)
X := element
return X
}
```

Code: Select all

```
Min(List*)
{
List._NewEnum().Next(,X)
for key, element in List
if (element < X)
X := element
return X
}
```

Examples of usage:

Code: Select all

```
; Basic Usage
MsgBox % Min(2,-11,4,3) ; -11
SimpleArrayofNumbers := [2,-11,4,3]
MsgBox % Min(SimpleArrayofNumbers*) ; -11
SimpleArrayofText := ["cherry","apple","pear","banana"]
MsgBox % Min(SimpleArrayofText*) ; apple
SimpleArrayofMixed := [2,1,"Tree","Pear",3]
MsgBox % Max(SimpleArrayofMixed*) ; Tree
AssociativeArray := {"one":"cherry","two":"apple","three":"pear","four":"banana"}
MsgBox % Max(AssociativeArray*) ; pear
```
