Before learning about data types, let’s first understand the number systems. 1. Decimal (十进制) The number system we use daily, with a base of 10, using digits 0-9. 123 = 1×10² + 2×10¹ + 3×10⁰ 2. Binary (二进制) With a base of 2, using digits 0 and 1. 1101₂ = 1×2³ + 1×2² + 0×2¹ … Read more
☆Star this public account to not miss any updates☆ Whether it is the CAN bus or any computer system, data is ultimately stored and processed in binary. However, for the convenience of human reading and writing, we extensively use hexadecimal and decimal. Below, I will explain in detail binary, decimal, and hexadecimal, as well as … Read more

Through the program, we can quickly calculate the representation of a decimal number in other bases. This article provides C language code for converting decimal to octal and hexadecimal.C language code. SinceC language conversion to binary is relatively complex, we will write about it at another time. #define _CRT_SECURE_NO_WARNINGS#include <stdio.h> int main() { int a; … Read more
1. BCD and Hexadecimal Conversion The test code is as follows: #include <stdio.h> #include <string.h> // Convert BCD to hexadecimal unsigned char bcd_to_hex(unsigned char bcd) { return ((bcd >> 4) * 10) + (bcd & 0x0F); } // Convert hexadecimal to BCD unsigned char hex_to_bcd(unsigned char hex) { return ((hex / 10) << 4) | … Read more
1. Base Conversion Data in computers is typically stored in binary form, but during programming and debugging, we often need to deal with decimal, octal, and hexadecimal systems. Therefore, mastering base conversion is an important part of learning C language. Editor 1.1 Basic Concepts of Number Systems Binary: Base 2, using digits 0 and 1. … Read more
