How to avoid losing pennies in calculated access fields?

Question

Microsoft Access

I import data from Excel to Access and carry out calculations in the request. At the same time, pennies are lost on each amount in the accessory.
Please tell me how can this be avoided?
Access field type: Numeric floating point. In theory, there should be no loss.
For example: 25/100000.

Answer 1

There is a special data type for currencies - Currency

Answer 2

These are not currencies, but volume indicators.
Table field type on the server: Double floating point and I have no rights to change it.
How to get around this problem?
