How to Set Decimal Accuracy for a Custom Float Field

Question

Image [1]
Hello Odoo experts 👋

I have a custom float field (e.g., price or rate)

I want it to display values with *3 decimal places*, like 0.000 There is *no Create button* on the form — I’m just trying to change how an existing float field is *displayed* in the UI  Thanks in advance !

Hi,

You can define the decimal precision while defining the field.
Try with the following code.
exchange_rate = fields.Float(string='Exchange.Rate', digits=(16, 3))
* You can change the precision from the UI.
Change the XML as
<field name="field_name" digits="[3,3]"/>

Hope it helps
