What is data type integer in Access?
Integers in Access come in 1, 2 and 4 byte varieties. The single byte number is named Byte (Range 0-255), the two-byte number is named Integer (-32768 to 32767) and then there is the Long Integer (-2 billion to 2 billion). Decimal numbers are so called fixed point numbers.

How are long integer numbers stored in dBase?
The Long Integer value stores whole numbers that range from about -2 billion to +2 billion. Or, you can choose the Double value to store numbers with decimals. This problem occurs because there is no Integer data type in dBase. dBase uses either Numeric or Float data types. Access maps Long Integers to the Numeric data type in dBase.
How to set the field size in access?
In the Field Properties pane, on the General tab, enter the new field size in the Field Size property. You can enter a value from 1 to 255. This number specifies the maximum number of characters that each value can have. For larger text fields, use the Memo data type (Long Text if using Access 2016).
How to export long integer numbers as double data type?
When you create a Microsoft Office Access table that contains long integer numbers and then you export that table as type dBase IV (.dbf), the numbers are converted to double data type and will show decimal places. For example, you may export the following table:
