+## `$sum()`
+__Signature:__ `$sum(array)`
+
+Returns the arithmetic sum of an array of numbers.  It is an error if the input array contains an item which isn't a number.

+- `$sum([5,1,3,7,4])` => `20`

+## `$max()`
+__Signature:__ `$max(array)`
+
+Returns the maximum number in an array of numbers.  It is an error if the input array contains an item which isn't a number.
+
+__Example__
+
+- `$max([5,1,3,7,4])` => `7`

+__Example__
+
+- `$min([5,1,3,7,4])` => `1`

+
+## `$count()`
+__Signature:__ `$count(array)`
+
+Returns the number of items in the `array` parameter.  If the `array` parameter is not an array, but rather a value of another JSON type, then the parameter is treated as a singleton array containing that value, and this function returns `1`.
+
+If `array` is not specified, then the context value is used as the value of `array`.
+
+__Examples__
+- `$count([1,2,3,1])` => `4`
+- `$count("hello")` => 1
+
+## `$append()`
+__Signature:__ `$append(array1, array2)`
+
+Returns and array containing the values in `array1` followed by the values in `array2`.  If either parameter is not an array, then it is treated as a singleton array containing that value.
+
+__Examples__
+- `$append([1,2,3], [4,5,6])` => `[1,2,3,4,5,6]`
+- `$append([1,2,3], 4)` => `[1,2,3,4]`
+- `$append("Hello", "World")` => `["Hello", "World"]`
+
+
+## `$sort()`
+__Signature:__ `$sort(array [, function])`
+
+Returns an array containing all the values in the `array` parameter, but sorted into order.  If no `function` parameter is supplied, then the `array` parameter must contain only numbers or only strings, and they will be sorted in order of increasing number, or increasing unicode codepoint respectively.
+
+If a comparator `function` is supplied, then is must be a function that takes two parameters:
+
+`function(left, right)`
+
+This function gets invoked by the sorting algorithm to compare two values `left` and `right`.  If the value of `left` should be placed after the value of `right` in the desired sort order, then the function must return Boolean `true` to indicate a swap.  Otherwise it must return `false`.
+
+__Example__
+```
+$sort(Account.Order.Product, function($l, $r) {
+  $l.Description.Weight > $r.Description.Weight
+})
+```
+
+This sorts the products in order of increasing weight.
+
+The sorting algorithm is *stable* which means that values within the original array which are the same according to the comparator function will remain in the original order in the sorted array.
+
+## `$reverse()`
+__Signature:__ `$reverse(array)`
+
+Returns an array containing all the values from the `array` parameter, but in reverse order.
+
+__Examples__
+- `$reverse(["Hello", "World"])` => `["World", "Hello"]`
+- `[1..5] ~> $reverse()` => `[5, 4, 3, 2, 1]`
+
+## `$shuffle()`
+__Signature:__ `$shuffle(array)`
+
+Returns an array containing all the values from the `array` parameter, but shuffled into random order.
+
+__Examples__
+- `$shuffle([1..9])` => `[6, 8, 2, 3, 9, 5, 1, 4, 7]`
+
+## `$distinct()`
+__Signature__ `$distinct(array)`
+
+Returns an array containing all the values from the `array` parameter, but with any duplicates removed.  Values are tested for deep equality as if by using the [equality operator](comparison-operators#equals).
+
+__Examples__
+- `$distinct([1,2,3,3,4,3,5])` => `[1, 2, 3, 4, 5]`
+- `$distinct(Account.Order.Product.Description.Colour)` => `[ "Purple", "Orange", "Black" ]`
+
+## `$zip()`
+__Signature:__ `$zip(array1, ...)`
+
+Returns a convolved (zipped) array containing grouped arrays of values from the `array1` ... `arrayN` arguments from index 0, 1, 2, etc.
+
+This function accepts a variable number of arguments.  The length of the returned array is equal to the length of the shortest array in the arguments.
+
+__Examples__
+- `$zip([1,2,3], [4,5,6])` => `[[1,4] ,[2,5], [3,6]]`
+- `$zip([1,2,3],[4,5],[7,8,9])` => `[[1,4,7], [2,5,8]]`

+
+Casts the argument to a Boolean using the following rules:

+| ------------- | ------ |
+| Boolean | unchanged |
+| string: empty | `false`|
+| string: non-empty | `true` |

+__Signature:__ `$not(arg)`

+Returns Boolean NOT on the argument.  `arg` is first cast to a boolean
+
+## `$exists()`
+__Signature:__ `$exists(arg)`
+
+Returns Boolean `true` if the arg expression evaluates to a value, or `false` if the expression does not match anything (e.g. a path to a non-existent field reference).
