main: if B0 > 0 then ( B1 = B0 ) and ( B2 = 43 ) ' 43 is + sign
if B0 < 0 then B1 = ( 65535 - B0 ) and ( B2 = 45 ) '45 is - sign

Hi precision,

Your IF statements are not precise

You should correct them as follows.

if B0 > 0 then 
 B1 = B0 
 B2 = 43
endif

if B0 < 0 then 
 B1 = 65535 - B0
 B2 = 45 
endif

B0 never equals to zero?

This is actually the idea of assigning a flag that will indicate negative status.
That is why I asked above, will you use this negative number in a math operation.

You can have a flag, like NegFlag=1 meaning you have the negative value, and NegFlag=0 meaning positive value.

If of course it can be useful in your case.
