W.W.E

W.W.E (World's Worst Esolang) is a programming language created by User:TheCanon2 that can only do popular problems.

Commands

W.W.E programs are read in nibbles. W.W.E has 15 commands.

Opcode	Symbol	Action
0000	h	Prints "Hello, World!"
0001	9	Prints the lyrics to the "99 bottles of beer" song
0010	q	Prints the program's source code
0011	f	Prints the Fibonacci numbers
0100	!	Prints the factorial of the input
0101	e	Prints all even numbers between 0 and the input
0110	c	Prints the input
0111	d	Prints the digital root of the input
1000	i	Interprets the input as Deadfish
1001	r	Prints the ROT13 of the input text
1010	p	Prints the value of pi
1011	t	Prints "0" and halt if the input is 0, or prints "1" indefinitely if the input is 1
1100	5	Prints the Fizzbuzz for values 1 to 100
1101	0	Makes an infinite loop
1110	l	Counts from 0 to the input
1111	*	Crashes the interpreter

Examples

Deadfish interpreter

¨

In hex:

A8

Unrelatedly prints the value of pi as well.

Crash

ÿ

In hex:

FF

Implementations

The following Python script is an interpreter.
