I try to compile your code. I downloaded the N-Bit_MATH.pbp include, but the compiler stops with this error message:
"Bad data type"

If I try to compile only the N-Bit_MATH.pbp (only for test) and its do not compile. Stops on first line:
REG_X VAR BYTE[PRECISION] BANK0 SYSTEM
with the same error message MCU is the same 16F628A, For test I try also 16F688 with the same result. Something I'am doing wrong, I think.

You need to define the constant PRECISION and assign it a value equal to the number of bytes to use for the values in the math routine. And you need to do this before including N-Bit. In this case it looks like Richard opted for 32bit values (4 bytes)

PRECISION CON 4 SYSTEM    '32bit values
Include "N-Bit_Math.pbp"

If you open the N-Bit file you'll find a link to the thread on this forum: http://www.picbasic.co.uk/forum/showthread.php?t=12433

Yes, right. I forgot this line. After putting this line as you say the code compiles OK. Now I do some testing and trying to understand the code.
