Axe can't handle negative numbers.

Did you try the solution of my previous post to replace the negative Q ?

@calc84maniac we can do -3→Q ?

Oooooh that makes a wave !!!
Nevermind, did you try the solution of my previous post to replace the negative Q ?

@calc84maniac we can do -3→Q ?

Yes. Technically how signed numbers work is that the range of values 32768 to 65535 are considered to be -32768 to -1. So when you store -3 to Q, you're storing the unsigned value 65533. When you add or subtract that with another number, it acts like -3 (due to the limited range of 16-bit numbers)

You can use a negative 3.  Signed $-3 is equal to unsigned $FFFD.  Text( only displays unsigned variables.  
You can use addition and subtraction with signed integers.  For division and multiplication, you must use ** or // respectively.  For comparisons and division, you use doubled operators.  
With this knowledge, you can write a routine that can display signed variables.

EDIT Double Ninja'd (I take way to long to write a post.)

Yes, that's how it works.  When doing multiplication and division, like calc84 said, though, you need to be aware you're using signed values.  Also, when using one negative number and adding it to a positive number to actually subtract it, be sure you use equal-bit-length numbers, since if A = 5 and {L1} = -3, A+{L1} doesn't yield 2, it gives 257 since {L1} is only 8 bits and you're doing 16 bit math.

Actually, you must use the normal multiplication (it works because it's so closely related to addition/subtraction). In Axe, ** is something different entirely called fixed-point multiplication.

ugh... Rewrite everything. Try this one, and tell the others if it worked. I'm going to sleep.
