Stuck again. I'm just not understanding this math
adval0 = 2904
result = adval0 / 15100
remainder = adval0 // 15100
result = 0
remainder is 2904
How do I get the acutal number it should be 0.192xxx?
I'm looking at dig but not sure if thats the right thing to use because it will not always be 2 digits...
adval 0 = 2904*10
result = adval/151
192
then use dig to move the places... and do something like
if > 9999
if > 999
to figure out where the . should be... Is this the best way to do it?

You aren't going to get .192xxx.Originally Posted by geckogrotto

PBP only deals with integer math, as stated in the PBP manual.
You'll have to write your own routines to get anything past the decimal point.

Ok how do I do that. I had edited my post while you were posting.

I see the edit, and you're on the right track, pretty much the only track.

Ok thanks,
I just didn't want to go down that road if there was a better way,

Well, you could use the floating point math routines on melabs website, microchip's site, etc.etc. or write your own.
The trick to doing it the way you've got set up above is to make sure that no individual variables overflow or underflow, no matter what values end up going into them. It just takes a bit of thinking thru it all...

I would like to not use those as I want to learn how to do this, but I sure could use some help i'm a bit lost here. Maybe just working on it too long.
The number I expect is 1-3 digits. Example
If the number is 123 it would be 1.23
If its 12 .12
If its just 1 then would be .01
I just can't seem to wrap my mind around how to actually accomplish this.
