As far as I can tell, that will work. Of course you should test it a few times

You can build a statue out of either 1'x1' blocks or 12'x12' blocks. The 1'x1' blocks will take a lot longer, but the final product is worth it.

No, you'll have to do that yourself. You can either convert it to decimal yourself, which is what I do, or you can make it positive, put out a negative sign if needed, then use bcall(_dispHL). But that will look ugly.

How can i generate a signed LUT for my sine routine?
and how can I calculate the square root of fixed-point numbers? Can this be done by using an 8-bit square-root routine?
