No, 200-300=65436.
65435 is -101 in two's complement because 65435+101 = 65536 which, when being truncated to 16 bits is 0.
If what you want is the difference between the two numbers while not...
Thanks Henrik, so Say A=200 B=300, C in this case will be 65535-100=65435, right? So if I take 65535 and minus it result, I should receive correct difference between A and B, right?
How about...
How about For..Next...Step
towlerg Yesterday, 18:13It will wrap around, 0-1=65535 provided the variable where the result is stored is a WORD.
HenrikOlsson Yesterday, 17:23Oh and by the way, currently I don't have access to machine with PBP, what will happen if C=A-B and B is > A ? all variables are word length. I need to determine difference between A and B, but...
CuriousOne Yesterday, 16:56Yes, I meant exactly that one.
In my case, there will be 16F886 running at 8mhz and maximum frequency will be around 2khz, so I guess, modulo variant will also work. Will assemble test circuit...
Wasn’t it just something like this?
not even timing of course because every fifth iteration takes slightly longer to execute, but could be balanced up if it mattered.
variable var word...
I don't know for sure but since it involves division my guess is that this is slower. Speed isn't always everything though.
Tell you what, why don't you try both ways and measure the difference,...
Thanks! this is way better and simpler. Speaking speed-wise, will this be faster in execution than my code with additional variable?

Re: Doing something at predefined amount of steps?
for the sign, so long as a & b are the same variable type:
Art Today, 05:24if (a - b) > a then
sign = 1 ' result will be negative
else
sign = 0 ' result will be positive or zero
