Decimal lost when settings were changed to integer due to rounded off.

Cause:


When a field's property settings are changed from Decimal Number to Integer Number, Access automatically rounds the decimals to the nearest whole number.
NOTE: These settings are changed when the number of decimals is changed in the 'Decimal Places' property box in the 'Field Properties' section of the Table Design window.

Solution:


Change the settings back to Decimal Number, and re-enter any data that was lost.
