Vui lòng viết bình luận nếu bạn thấy bất cứ điều gì không chính xác hoặc bạn muốn chia sẻ thêm thông tin về chủ đề thảo luận ở trên Ghi chú cá nhân của tôi arrow_drop_up Cứu Vui lòng Đăng nhập để nhận xét.thập phân () trong Python là gì?Trong Python, có một mô-đun tên là Decimal, được sử dụng để thực hiện một số tác vụ liên quan đến dấu phẩy động thập phân . Mô-đun này cung cấp số học dấu phẩy động được làm tròn chính xác. Để sử dụng nó, trước tiên chúng ta cần nhập mô-đun thư viện chuẩn Decimal. nhập số thập phân.
Tại sao 0. 1 0. 2 không phải là 0. 3 con trăn?Tương tự, giá trị nhị phân của 0. 2 được lưu dưới dạng 0. 001100110. Bây giờ, khi bạn thêm 0. 1 + 0. 2 bằng Python (hoặc bằng một số ngôn ngữ lập trình khác), Python chuyển đổi 0. 1 và 0. 2 về dạng nhị phân. Sau đó, nó thực hiện phép cộng. Kết quả sẽ không bao giờ bằng 0. 3 chính xác . |
