strange A2D 5V scaling result - 16F819

[Darrel Taylor]

While it is incorrect, the results are not strange at all.

The Modulus operator only returns a decimal number if you are dividing by a factor of 10 (10,100,1000).

When you // 1024, the result will be from 0 to 1023.
The numbers at 201, 202 are where the value goes over 1000, but you are displaying the lowest 3 digits.

For 3 decimals, the easiest way to do it is ...

W0 = A2Dvalue * 5000
W0 = DIV32 1023
