6 bits, 12 bytes

6 bits, 12 bytes is the fifth ___ bits ___ bytes language and the first one to not be a joke, created by Europe2048.
== Characters ==
Here is the standard character map used for outputting, one character per byte:

== Commands ==
"top value of the stack" is shortened to "top value".
Do A on B means to pop B, and push operation A applied to B.
Talk before you change! (if you aren't the owner)
Byte	Name 	Shortened	Action
00 	null 	* 	Does absolutely nothing.
01 	duplicate 	. 	Duplicates the top value.
02 	over 	, 	Duplicates the second-to-top value.
03 	flip 	: 	Flips the top two values.
04 	flip all 	↕ 	Flips the entire stack.
05 	pop 	◌ 	Pops the top value.
06 	add 	+ 	Adds the top two values.

0d 	sine 	∿ 	
0e 	number 	# 	Prints the top value as a number.
0f 	print 	→ 	Prints the top value as a character (modulo 256). Printing a bell character will play a sound.

18 	eight 	8 	Pushes 8.
19 	nine 	9 	Pushes 9.
1a 	push 	↑ 	Pushes a number on to the stack.
1b 	pi 	π 	Pushes pi.
1c 	euler 	e 	Pushes Euler's number.
1d 	byte 	• 	Pushes 256.
1e 	round 	[ 	Rounds as usual.
1f 	ceiling 	⌈ 	Rounds away from 0.
20 	jump 	↷ 	Jumps to the corresponding instruction.
21 	start loop 	( 	Jumps to the corresponding ) if the top value is ≤0.
22 	end loop 	) 	Goes back to the corresponding ( if the top value is >0.
23 	input 	↓ 	Input a number and push it to the stack.
24 	increment 	i 	Increases the top value by 1.
25 	decrement 	d 	Decreases the top value by 1.

39 	? 	? 	?
3a 	? 	? 	?
3b 	random 	⚂ 	Pushes a random number between 0 and 1.
3c 	un 	° 	When put before a command, inverses it.
3d 	cycle 	↻ 	Toggles cycle mode: the program goes back to the first command after finishing the last. Cycle mode is off by default.
3e 	clear 	□ 	Pops everything.
3f 	end 	■ 	Ends the program.
== Order ==
When using a command like subtract -, the top value is the first argument. So,
 25-# **** **** ****
outputs 3, but
 52-# **** **** ****
outputs -3.
== Numbers ==
Numbers are represented in six bits, using the standard binary representation.
