ZPE features many built-in functions including functions that simplify mathematical problems such as the greater_than_all function, the to_binary, to_octal and to_hexadecimal functions as well as many functions to streamline processing of arrays such as list_process, list_find_duplicates and list_auto_populate.
Finds the length of an array or of a quasi-array with keys with an optional prefix such as "data1", "data2", etc. It uses an exponential search algorithm to find the length, so as to use as few table lookups as possible. This algorithm is useful for arrays that use metatables (e.g. frame.args) and for quasi-arrays.

Folds can be regarded as consistently replacing the structural components of a data structure with functions and values. Lists, for example, are built up in many functional languages from two primitives: any list is either an empty list, commonly called nil ([]), or is constructed by prefixing an element in front of another list, creating what is called a cons node ( Cons(X1,Cons(X2,Cons ...
CaRMetal can also use the JavaScript objects like arrays, useful to make statistics on geometric figures; date object, useful to measure time; String and RegExp objects, which make it easy to implement L-systems; General JavaScript objects can be used to create new geometric objects like complex numbers, matrices etc.
Note how the use of A[i][j] with multi-step indexing as in C, as opposed to a neutral notation like A(i,j) as in Fortran, almost inevitably implies row-major order for syntactic reasons, so to speak, because it can be rewritten as (A[i])[j], and the A[i] row part can even be assigned to an intermediate variable that is then indexed in a separate expression.
Note that the function does not use keys, which means that the sequential structure is completely recorded by the binary search tree’s edges. For traversals without change of direction, the ( amortised ) average complexity is O ( 1 ) , {\displaystyle {\mathcal {O}}(1),} because a full traversal takes 2 n − 2 {\displaystyle 2n-2} steps for a ...
In computer science, an associative array, map, symbol table, or dictionary is an abstract data type that stores a collection of (key, value) pairs, such that each possible key appears at most once in the collection. In mathematical terms, an associative array is a function with finite domain. [1] It supports 'lookup', 'remove', and 'insert ...
