With the OSP3000 control the decimal is an option...
The resolution is no different, but the way its handled(read/interpreted) by the control is different.
With the decimal option, you can use any of the following:
0.0001, .0001, .001,.0010,.01,.0100 etc....
But without the decimal option, you have to work from the 4th decimal point and work to the front. And you have to use the trailing zeros, but not the leading zeros.
So 1.0101 would be 10101
.0001 could be 1,01,001,0001,or 00001
.1" would be have to be written as 1000
Basically, from what I can see of the decimal option, its mainly does two things... simplifies programming and allows using less characters therefore reducing memory used because you can drop tailing zeros. Though it does seem to be a bit of a wash if you are working under 1" because because with the decimal, you would have all the leading zeros following the decimal.
Hope that makes sense....
