Operators

check notes below for table interpretation

Nulary Functions (Nilads)

Unary Functions (Monads)

Assuming a as top of stack

	Fraction	String (1 char)	List
↑	a+1	next char in codebase	Map ↑ a
↓	a-1	prev char in codebase	Map ↓ a
!	Factorial of a	Factorial of c(a)	Map ! a

Binary Functions (Dyads)

Assuming b as top of stack, a below b

	Frac×Frac	Frac×Str	Str×Frac	Str×Str	Frac×List	List×Frac	Str×List	List×Str	List×List
+	a+b	u(a+cb)	ibid.	u(ca+cb)	M +a b	ibid.	M +ca b	ibid.	M + zip(a,b)

Notes:

• c(char) is the value of char in the codebase; ca means c(a)

• u(n) is the char with codebase n; ua means u(a)

• unless stated, string operators consider a circular codebase; eg. i=(i+1)%256

• Fraction x rounds to ⌊x⌋ when needed as int

• Map op/M op means map operation op over elements of String/List (recursively with lists of lists)

• unless stated, zip/zipWith cycle the smaller list
