I have a list of numbers that have two decimal places. I have checked that all numbers have maximum of two decimal places by extending the decimal to 30 places and all digits past the second decimal show as zero. when I use SUM to add these numbers the value shows as a two-digit value as expected. But if I extend the decimal places on the solution it shows a '2' in the ninth decimal place. Anyone know what I am missing here? I have done some trial and error sums to try to locate the culprit unsuccessfully as I get different results.
