Add case decimal.NullDecimal, because why not

// Directly handle decimal.Decimal type
f.d.Decimal = v
f.d.Valid = true
return nil
default:
// Use the normal NullDecimal scan for other types
return f.d.Scan(value)
}
}

// Value implements the driver.Valuer interface for database serialization.
func (f FixedPoint) Value() (driver.Value, error) {
if f.IsValid() {
return nil, nil
}
return f.d.Decimal.Value()
}
