Eval op-code

I was using the 'Eval' Op-code to add 39 fields which all had the
attributes of 4 in length and 2 decimal places into a Total field of 6 in
length and 2 decimal places.

The problem that I was having is that the sum of the 39 field didn't
include anything to the right of the decimal place in my 'Total' field
unless the sum of the decimal places reached the next whole number.

Example:

Field 1 = 00.25
Field 2 = 02.25
Field 3 = 00.25

My Total would = 2.00

If I added a Field 4 = .25 then my Total would be 3.00

So I broke down the Eval and noticed the the maximum number of field I can
use to get the correct decimal answer in my Total field was 29.

Is this by design?
