 		[b]Differences between packed arrays, typed arrays, and untyped arrays:[/b] Packed arrays are generally faster to iterate on and modify compared to a typed array of the same type (e.g. [PackedInt64Array] versus [code]Array[int][/code]). Also, packed arrays consume less memory. As a downside, packed arrays are less flexible as they don't offer as many convenience methods such as [method Array.map]. Typed arrays are in turn faster to iterate on and modify than untyped arrays.

-				Sorts the array.
-				[b]Note:[/b] The sorting algorithm used is not [url=https://en.wikipedia.org/wiki/Sorting_algorithm#Stability]stable[/url]. This means that values considered equal may have their order changed when using [method sort].
-				[b]Note:[/b] Strings are sorted in alphabetical order (as opposed to natural order). This may lead to unexpected behavior when sorting an array of strings ending with a sequence of numbers. Consider the following example:
+				Sorts the array in ascending order. The final order is dependent on the "less than" ([code]&gt;[/code]) comparison between elements.
 				[codeblocks]
 				[gdscript]
-				var strings = ["string1", "string2", "string10", "string11"]
-				strings.sort()
-				print(strings) # Prints [string1, string10, string11, string2]
+				var numbers = [10, 5, 2.5, 8]
+				numbers.sort()
+				print(numbers) # Prints [2.5, 5, 8, 10]
 				[/gdscript]
 				[csharp]
-				var strings = new Godot.Collections.Array { "string1", "string2", "string10", "string11" };
-				strings.Sort();
-				GD.Print(strings); // Prints [string1, string10, string11, string2]
+				var numbers = new Godot.Collections.Array { 10, 5, 2.5, 8 };
+				numbers.Sort();
+				GD.Print(numbers); // Prints [2.5, 5, 8, 10]
 				[/csharp]
 				[/codeblocks]
-				To perform natural order sorting, you can use [method sort_custom] with [method String.naturalnocasecmp_to] as follows:
-				[codeblock]
-				var strings = ["string1", "string2", "string10", "string11"]
-				strings.sort_custom(func(a, b): return a.naturalnocasecmp_to(b) &lt; 0)
-				print(strings) # Prints [string1, string2, string10, string11]
-				[/codeblock]
+				[b]Note:[/b] The sorting algorithm used is not [url=https://en.wikipedia.org/wiki/Sorting_algorithm#Stability]stable[/url]. This means that equivalent elements (such as [code]2[/code] and [code]2.0[/code]) may have their order changed when calling [method sort].

 			<return type="void" />

 			<description>
-				Sorts the array using a custom method. The custom method receives two arguments (a pair of elements from the array) and must return either [code]true[/code] or [code]false[/code]. For two elements [code]a[/code] and [code]b[/code], if the given method returns [code]true[/code], element [code]b[/code] will be after element [code]a[/code] in the array.
-				[b]Note:[/b] The sorting algorithm used is not [url=https://en.wikipedia.org/wiki/Sorting_algorithm#Stability]stable[/url]. This means that values considered equal may have their order changed when using [method sort_custom].
-				[b]Note:[/b] You cannot randomize the return value as the heapsort algorithm expects a deterministic result. Randomizing the return value will result in unexpected behavior.

+				Sorts the array using a custom [Callable].
+				[param func] is called as many times as necessary, receiving two array elements as arguments. The function should return [code]true[/code] if the first element should be moved [i]behind[/i] the second one, otherwise it should return [code]false[/code].
+				[codeblock]
 				func sort_ascending(a, b):
-				    if a[0] &lt; b[0]:
+				    if a[1] &lt; b[1]:
 				        return true
 				    return false
 
 				func _ready():
-				    var my_items = [[5, "Potato"], [9, "Rice"], [4, "Tomato"]]
+				    var my_items = [["Tomato", 5], ["Apple", 9], ["Rice", 4]]
 				    my_items.sort_custom(sort_ascending)
-				    print(my_items) # Prints [[4, Tomato], [5, Potato], [9, Rice]].
+				    print(my_items) # Prints [["Rice", 4], ["Tomato", 5], ["Apple", 9]]
 
-				    # Descending, lambda version.
+				    # Sort descending, using a lambda function.
 				    my_items.sort_custom(func(a, b): return a[0] &gt; b[0])
-				    print(my_items) # Prints [[9, Rice], [5, Potato], [4, Tomato]].
-				[/gdscript]
-				[csharp]
-				// There is no custom sort support for Godot.Collections.Array
-				[/csharp]
-				[/codeblocks]
+				    print(my_items) # Prints [["Apple", 9], ["Tomato", 5], ["Rice", 4]]
+				[/codeblock]
+				It may also be necessary to use this method to sort strings by natural order, with [method String.naturalnocasecmp_to], as in the following example:
+				[codeblock]
+				var files = ["newfile1", "newfile2", "newfile10", "newfile11"]
+				files.sort_custom(func(a, b): return a.naturalnocasecmp_to(b) &lt; 0)
+				print(files) # Prints ["newfile1", "newfile2", "newfile10", "newfile11"]
+				[/codeblock]
+				[b]Note:[/b] In C#, this method is not supported.
+				[b]Note:[/b] The sorting algorithm used is not [url=https://en.wikipedia.org/wiki/Sorting_algorithm#Stability]stable[/url]. This means that values considered equal may have their order changed when calling this method.
+				[b]Note:[/b] You should not randomize the return value of [param func], as the heapsort algorithm expects a consistent result. Randomizing the return value will result in unexpected behavior.
