| arrayAppend | Appends an array element to an array. |
| arrayAvg | Calculates the average of the values in an array. |
| arrayClear | Deletes the data in an array. |
| arrayContains | Searches an array for the presence of a specified object. The function searches simple objects such as strings and numbers or complex objects such as structures. String searches are case-sensitive. This function does not support searche for COM and CORBA objects. |
| arrayDelete | Deletes an element from an array. It does not support COM and CORBA objects. |
| arrayDeleteAt | Deletes an element from a specified position in an array. |
| arrayFind | This function performs a case-sensitive search on an array for a specified object. The function can search for simple objects such as strings or numbers and complex objects such as structures. It does not support COM and CORBA objects. |
| arrayFindNoCase | This function performs a case-insensitive search on an array for a specified object. The function can search for simple objects such as strings or numbers and complex objects such as structures. It does not support COM and CORBA objects. |
| arrayInsertAt | Inserts a value into an array. Array elements whose indexes are equal to or greater than the new position are incremented by one. The array length increases by one. |
| arrayIsDefined | Determines whether an array element is defined. |
| arrayIsEmpty | Determines whether an array is empty of data elements. |
| arrayLen | Determines the number of elements in an array. |
| arrayMax | Array maximum function. |
| arrayMin | Array minimum function. |
| arrayNew | Creates an array of 1–3 dimensions. Index array elements with square brackets: [ ]. |
| arrayPrepend | Inserts an array element at the beginning of an array. |
| arrayResize | Resets an array to a specified minimum number of elements. Resetting can improve performance, if used to size an array to its expected maximum. For more than 500 elements, use ArrayResize immediately after using the ArrayNew tag. |
| arraySet | In a one-dimensional array, sets the elements in a specified index range to a value. Useful for initializing an array after a call to ArrayNew. |
| arraySort | Sorts array elements numerically or alphanumerically. |
| arraySum | Array sum function. |
| arraySwap | Swaps array values of an array at specified positions. This function is more efficient than multiple cfset tags. |
| arrayToList | Converts a one-dimensional array to a list. |
| isArray | Determines whether a value is an array. |
| listToArray | Copies the elements of a list to an array. |
