You have column number, but if I put

            CRUD::addField([
                'name' => 'usd',
                'tab' => 'Prices',
                'decimals' => 3, <-- this not working because I need to put step
                'attributes' => [
                    'step' => "0.001", <--- maybe you need to put with decimals the step attribute, because html5 validation don't give me permission to save form.
                ],
                'label' => 'Price in USD',
                'type' => 'number',
                'prefix' => '$',
                'suffix' => ' USD',
            ]);

html5 validation don't

I mean if
decimal=1
step=0.1

decimal=2
step=0.01

decimal=3
step=0.001

You're right about the relationship between decimals and the step attribute in number fields. The HTML5 validation for number inputs requires the step attribute to match the decimal precision you want to allow.

In Backpack, when using a number field, you need to explicitly set the attributes with the appropriate step value to allow decimal inputs. The decimals parameter alone won't configure the HTML input validation correctly.

Your implementation is correct:

CRUD::addField([
    'name' => 'usd',
    'tab' => 'Prices',
    'decimals' => 3,
    'attributes' => [
        'step' => "0.001",
    ],
    'label' => 'Price in USD',
    'type' => 'number',
    'prefix' => '$',
    'suffix' => ' USD',
]);

This is consistent with the Backpack documentation and issues that have been reported. The step attribute is needed to allow decimal inputs in HTML5 number fields Decimal Separator on Number FieldType.

As you correctly pointed out, the relationship between decimals and step should be:

• For 1 decimal place: step="0.1"
• For 2 decimal places: step="0.01"
• For 3 decimal places: step="0.001"

Alternatively, you could use step="any" to allow any decimal input, but then you'd rely solely on server-side validation for precision Number field decimal shows wrong value.

Note that the decimals parameter is primarily used for display formatting in columns, not for input validation in fields Number fields do not accept decimals.
