Do you want the warning to be displayed right on the change of that field, or when the user tries to save the record?

In your Case use an on_change method:

<field name="your_float_field" on_change="your_onchange_method(your_float_field)"/>

And in your .py file:

def your_onchange_method(cr, uid, ids, float_value, context=None):
    res = {}
    if float_value < 0:
        res['warning'] = {'title': 'Warning Title', 'message': '''Warning Message'''}
        res['value'] = {'your_float_field': abs(float_value)}
    return res

_columns = {
    'your_float_field': field.float('Field Name'),
}

This will display a warning message and set the float value to a positive value.

Regards.

Hi,

Add _constraints in py file, try below code

def _check_qty(self, cr, uid, ids, context=None):
    for order in self.browse(cr, uid, ids, context=context):
        if order.your_field < 0:
            return False
   return True

_constraints = [
           (_check_qty, ' your_field cannot be negative !', ['your_field']),
]
