Bàn luận{IDE} first, before moving on to the solution.
Cho một số trong số thập phân chuyển đổi nó thành số nhị phân, bát phân và thập lục phân. Đây là chức năng để chuyển đổi thập phân thành nhị phân, thập phân thành bát phân và thập phân thành thập lục phân.
Được đề xuất: Vui lòng thử cách tiếp cận của bạn trên {IDE} trước, trước khi chuyển sang giải pháp.
Một giải pháp là sử dụng phương pháp được thảo luận trong bài dưới đây.
Chuyển đổi từ bất kỳ cơ sở nào sang thập phân và ngược lại
Python cung cấp các chức năng trực tiếp cho các chuyển đổi cơ sở tiêu chuẩn như bin (), hex () và oct ()

Chuyển đổi cơ sở-10 thành cơ sở-16 Bạn chia số cho số mũ (16) và tiếp tục chia kết quả cho đến khi thương số là 0. Ở mỗi bước bạn nhân phần còn lại với 16 để nhận giá trị hex.divide the number by the exponent (16) and keep dividing the result until the quotient is 0. At each step you multiply the remainder by 16 to get the hex value.
Trong Python, bạn có thể sử dụng hàm hex () để chuyển đổi từ giá trị thập phân sang giá trị thập lục phân tương ứng của nó hoặc hàm int () với cơ sở 16 cho hệ thống số thập lục phân.int() function with base 16 for the hexadecimal number system.
Có một cách để chuyển đổi sang các cơ sở khác nhau bằng cách chia số cơ sở 10 cho cơ sở và lấy phần còn lại và lặp lại cho đến khi nó không chia hết và viết thương số theo sau là tất cả các phần còn lại.(Vd.dividing the base 10 number by the base and taking the remainder and repeating until it is not divisible and write the quotient followed by all the remainders. (EX. 50/6 = 8 R 2, 8/6 = 1 R2 so 50 in base 6 would be 122).
