How to change the number of decimal places in Odoo

In Odoo there is an option to change the number of decimal places for already defined decimal.precision objects: “Product Price“, “Discount“, “Stock Weight“, “Payment Terms“, “Product Unit of Measure“, “Payroll” and “Payroll Rate“.

You can do that by going to Settings >> Technical >> Database Structure >> Decimal Accuracy, choosing one of the defined objects and updating the field “Digits“.

Also, you can create a new decimal.precision object. In such a case you need to update the backend code with it.

Every QWeb report needs to have div with class “page”

The PDF body for every QWeb report that you create needs to be inside a div with a class “page”. That means if you don’t have such class in your report its body will be a blank page.

For Example, the following report will show the text “Sales Order” and its name.

<div class="page">
    <h2>Sales Order <span t-field=""/></h2>

For example, if you want to display amount_total field in your new report with monetary widget the value for the display_currency parametar should be o.currency_id instead of “o.currency_id”

<span t-field="o.amount_total" t-options='{"widget": "monetary", "display_currency": o.currency_id'/>

How to compare two float numbers in Odoo

If you need to compare two float numbers in Odoo you should use the method float_compare. This method allows you to have more accurate results in your calculation. Except for the values that need to be compared this method as arguments receives precision_digits and precision_rounding. You need to choose only one of these arguments because the precision must be by digits or rounding.

For example, if you want to compare 8.945 and 8,946 with precision_digits 2 the return result will be 0 that means both values are same. In a case when precision_digits is 3 the return value will be -1 that means the second value is bigger than the first.

# Odoo 9
from import float_compare

# Odoo 10
from import float_compare

>>> float_compare(8.945, 8.946, precision_digits=2)
>>> 0

>>> float_compare(8.945, 8.946, precision_digits=3)
>>> -1

>>> float_compare(8.946, 8.945, precision_digits=3)
>>> 1

You can find more how this method works in the Github Odoo repository
