NS!

NS! (or Number Stack!) is a stack-based esoteric language made by User:Zopium that focuses on numbers. It is case-sensitive, so if you enter something like 3a*3+#, it wont print the 33rd ASCII character (!).

Commands

Command	Purpose
0, 1, 2, 3, ... D, E, F	Pushes the number onto the stack.
?	Asks for user input, if it returns NaN, it wont push the value to the stack.
+	Pops the two values from the stack, adds them together, and pushes the result onto the stack.
-	Pops the two values from the stack, subtracts them together, and pushes the result onto the stack.
*	Pops the two values from the stack, multiplies them together, and pushes the result onto the stack.
/	Pops the two values from the stack, divides them together, floors the result, and pushes the result onto the stack.
%	Pops the two values from the stack, divides them together, and pushes the remainder onto the stack.
P	Pops the two values from the stack, raises the first to the power of the second, and pushes the result onto the stack.
^	Pops the two values from the stack, does a bitwise XOR with the values and pushes the result onto the stack.
&	Pops the two values from the stack, does a bitwise AND with the values and pushes the result onto the stack.
|	Pops the two values from the stack, does a bitwise OR with the values and pushes the result onto the stack.
>	Pops the two values from the stack, right shifts the first value's bits by the second value and pushes the result onto the stack.
<	Pops the two values from the stack, left shifts the first value's bits by the second value and pushes the result onto the stack.
#	Pops a value from the stack and prints an ASCII character with that value.
$	Basically the same as #, but after the value is popped, it gets pushed back in.
