Example: Increasing the decimal precision for result fields in Query for
iSeries
Figure 5 has a result field with a current maximum precision of 31 (length) and 2 (decimal positions). The
decimal precision was derived from the calculation 31-29+9-9.
Note: The presentation length for RESULTA a would be 31,9. You can see this by pressing ″F13=Layout″.
To increase the decimal precision for the result field (RESULTA):
1. Assign each input field (PRN299A, PRN299B) directly to a result field.
2. Replace the input fields used in the original result field expression with the new result fields
(RESULT269, RESULT295).
3. Change the corresponding length (Len) and decimal positions (Dec) for the new result fields so that
the decimal precision sufficiently increases (see the previously listed formulas) for the original result
field (RESULTA).
In Figure 6 on page 191the RESULTA decimal precision is changed from 2 to 9. The new decimal
precision was derived from the calculation 31-26+9-5.
