Operators

Operators are used to modify data and return it, for example to do arithmetic. They are classified as nilary, unary, binary or ternary depending on the number of arguments they take, and non-lazy or lazy depending on whether they take their arguments in evaluated form or non-evaluated form. There are also some operators that use their own syntax. In verbose mode they take the form of functions, similar to commands. Operands are denoted by x, y, z and a respectively.

Non-lazy

Nilary

Operator	Verbose	Returns
Ｓ	InputString	The next input as a string.
Ｎ	InputNumber	The next input as a number.
‽	Random	0 or 1 with equal chance.
ＫＡ	PeekAll	Every cell on the canvas, from left to right and top to bottom.
ＫＭ	PeekMoore	Cells in a Moore neighborhood around the cursor
ＫＶ	PeekVonNeumann	Cells in a Von Neumann neighborhood around the cursor.
ＫＫ	Peek	The character under the cursor.
ⅈ	x/i	Current cursor x-position.
ⅉ	y/j	Current cursor y-position.

Unary

Operator	Verbose	Returns
±	Negate	-x.
Ｌ	Length	The length of x.
¬	Not	False if x is truthy, else True if x is falsy.
Ｉ	Cast	x as a string if it is a number, or x as a number if it is a string.
‽	Random	A random integer between 0 and x, each number having equal chance to appear, or a randomly selected character if x is a string or a random element if x is a list.
Ｖ	Evaluate/eval	The result after executing x as a string.
⊟	Pop	The last value in x, after removing it from x.
↧	Lowercase	The lowercase equivalent of x if it has one.
↥	Uppercase	The uppercase equivalent of x if it has one.
⌊	Minimum	The minimum value in x.
⌈	Maximum	The maximum value in x.
℅	Character/Ordinal/chr/ord	The character code of x if x is a character, or the character x is the character code of if x is an integer.
⮌	Reverse	x reversed.
～	BitwiseNot	The 2's complement of x.
Σ	Sum	The sum of all elements in x if it is an array, digital sum if it is a number, sum of all numbers or digital sum if it is a string depending on whether it can be parsed as a single number.
Π	Product	The product of all elements in x if it is an array, digital product if it is a number, product of all numbers or digital product if it is a string depending on whether it can be parsed as a single number.
⊕	Incremented/++	x+1 if it is a number, ... if it is a string. Vectorizes.
⊖	Decremented/--	x-1 if it is a number, ... if it is a string. Vectorizes.
⊗	Doubled/***	x*2 if it is a number, ... if it is a string. Vectorizes.
⊘	Halved/\\	x/2 if it is a number, ... if it is a string. Vectorizes.
ＵＶ	PythonEvaluate/pyeval	eval(x).

Binary

Operator	Verbose	Returns
⁺	Add/Plus	x+y. Vectorizes.
⁻	Subtract/Minus	x-y, or x with y deleted if both x and y are strings. Vectorizes.
×	Multiply/Times	x*y. Vectorizes.
÷	IntDivide/IntegerDivide	x//y. Vectorizes.
∕	Divide	x/y, or x split by y if x and y are strings, or x reduced using y if y is a function. Vectorizes.
﹪	Modulo	x%y. Note that this can be used to format strings.
⁼	Equals	Whether x is equal to y.
‹	Less	<
›	Greater	>
…·	InclusiveRange	[x, y] over the integers or characters.
…	Range	[x, y) over the integers or characters.
…	CycleChop/Mold	x repeated and chopped to length y.
Ｘ	Exponentiate/Exponent/Power	x to the power of y.
§	AtIndex	x[y], wrapping if needed.
⊞Ｏ	PushOperator	x after pushing y to x.
⪫	Join	The result of joining x with y.
⪪	Split	The result of splitting x with y.
⌕Ａ	FindAll	The indices of y in x.
⌕	Find	The index of y in x.
◧	PadLeft	The result of left-padding x with y.
◨	PadRight	The result of right-padding x with y.
№	Count	The number of occurrences of y in x.

Quaternary

Operator	Verbose	Returns
✂	Slice	Every a items of x starting at y until (but not including) z.

Lazy

Binary

Operator	Verbose	Returns
∧	And/and	y if x and y are both truthy else False. Short-circuits.
∨	Or/or	y if y is truthy, else x if x is truthy, else False. Short-circuits.

Ternary

Operator	Verbose	Returns
⎇	Ternary	y if x is truthy else z.

Other

Operator	Verbose	Arguments	Returns
ＫＤ	PeekDirection	exp dir	The cells in a line of length x in the direction y from the cursor, including the cell under the cursor.
Ｅ	Each/Map	exp exp	An array arr where arr[i] is y(x[i]). During evaluation of y, the loop variable and index are stored in the first two free variables in ικλμνξπρςστυφχψωαβγδεζηθ.
ＵＰ	PythonFunction	str lst	Gets the function with a return value x from Python, and runs it with y as arguments.
