Implementation method of converting hexadecimal to binary in Go language

Go language is an efficient and concise programming language that is widely used in various fields. In the Go language, we often encounter situations where base conversion is required, such as converting hexadecimal numbers into binary numbers. In this article, we will introduce how to implement hexadecimal to binary conversion in the Go language and provide specific code examples.

First of all, it needs to be clear that in computers, conversion between hexadecimal and binary is a very common operation. Hexadecimal is a base system that uses 16 different symbols (0-9, A-F) to represent numbers, while binary is a base system that uses 0 and 1 to represent numbers. Therefore, to convert a hexadecimal number into a binary number, we need to convert each hexadecimal digit into the corresponding 4-digit binary number.

Next, we will give a simple Go language function to convert a hexadecimal string into the corresponding binary string:

package main

import (
    "fmt"
    "strconv"
)

func hexToBinary(hex string) string {
    binary := ""

    for _, char := range hex {
        num, _ := strconv.ParseInt(string(char), 16, 64)
        binary = fmt.Sprintf(" b", num)
    }

    return binary
}

func main() {
    hexNum := "1A8F" // The hexadecimal number to be converted
    binaryNum := hexToBinary(hexNum)
    fmt.Printf("The hexadecimal number %s is converted to binary number %s
", hexNum, binaryNum)
}

In the above code, we define a hexToBinary function, which accepts a hexadecimal string as a parameter, and then converts each character in it to the corresponding 4-digit binary numbers and concatenate them to get the final binary string. In the main function, we call the hexToBinary function and output the conversion result.

Through the above code examples, we can see that it is not complicated to convert hexadecimal to binary in Go language. We only need to process each hexadecimal character in turn and use strconv The relevant functions in the package can be used for conversion.

In general, the Go language provides a rich standard library and powerful functions, making it easier and more efficient to write various hexadecimal conversion codes. I hope this article can help readers who are interested in the Go language and gain a deeper understanding of base conversion operations.
