Functions

Functions operate on data, which can either be an argument or the result of another function.

Single Byte Nilads

Character	Function
®	Retrieve the value from the register
³	First input (third command line argument) or 100
⁴	Second input (fourth command line argument) or 16
⁵	Third input (fifth command line argument) or 10
⁶	Fourth input (sixth command line argument) or " "
⁷	Fifth input (seventh command line argument) or "\n"
⁸	Sixth input (eighth command line argument) or []
⁹	Seventh input (ninth command line argument) or 256
⍺	Left Argument or 0.1
⍵	Right Argument or 1 (TODO)
π	Pi

Single Byte Monads

Character	Function
~	Bitwise NOT
√	Square Root
‘	Decrement
’	Increment
¹	Identity
²	Square
!	Factorial(z) if z is an integer and z > 0, -Factorial(abs(z)) if z is an integer and z < 0, Gamma(z + 1) otherwise
A	Absolute Value
B	Convert integer to binary

F	Flatten list completely
G	Format as a grid
H	Convert integer to hexadecimal
Ḣ	Pop and return the first value of a list
İ	Inverse; 1 / z for integers and upside-down (wherever applicable) for characters
J	Range of length (range(len(z)))
L	Length
Ḷ	Lowered Range; 0 .. z - 1

Ṭ	Return an array of 1 and 0 with 1 at the indices of z
U	Return the unique elements of z in order by their first occurrence
W	Wrap; return [z]
Ẇ	Sublists; return all contiguous subslices of z
X	Random element of a list, random integer in the range 1 .. z if z is an integer, random float from 0 to z if z is a float
Ẏ	Tighten; flatten by 1 level
Z	Integer Partitions; all lists of positive integers that sum to z
∆	Deltas; return differences of consecutive pairs
↔	Reverse each sublist to the last level
↕	Reverse a list; does not vectorize
¬	Logical NOT; vectorizes
↙	Transpose a matrix
