Как я могу преобразовать номер блока в тип Integer в модуле субстрата?

Я тестирую субстрат вне сети, я хочу получить текущий номер блока, а затем выполнить некоторые вычисления, как в приведенном ниже коде if (get_block / 10 == 0), и я получаю некоторую ошибку. Как я могу преобразовать номер блока в целочисленный тип?

мой код

use frame_support::{decl_storage, decl_module, dispatch::DispatchResult, debug};

use frame_system::{ensure_signed, offchain};

use sp_runtime::{
  offchain::http,
  transaction_validity::{
    TransactionValidity, TransactionLongevity, ValidTransaction, InvalidTransaction
  }
};

pub trait Trait: frame_system::Trait {}

decl_storage! {
    trait Store for Module<T: Trait> as Runtime_example {
        SubjectCount: u32;        
    }
}
decl_module! {
    pub struct Module<T: Trait> for enum Call where origin: T::Origin {
        fn offchain_worker(block: T::BlockNumber){
            let get_block = block;
            if (get_block / 10 == 0) {  
               debug::info!("print !!!!!!!!!!!!!!!!");               
            }            
        }
    }
}
