How to convert byte type to int type in golang

In Golang, the byte type is an unsigned 8-bit integer, and the int type is a signed integer. Therefore, when we need to convert the byte type to the int type, we need to perform type conversion.

Golang provides some built-in type conversion functions that can easily convert values ​​of different types into each other. For byte to int conversion, we can use the built-in int function to convert the byte type to the int type.

The sample code is as follows:

package main

import "fmt"

func main() {
    var b byte = 255
    var i int = int(b)
    fmt.Println(i)
}

In the above example, we first define a variable b of byte type, whose initial value is 255. Then the variable b is converted to the int type by calling the int function, and the returned result is assigned to the variable i.

Finally, we use the Println function in the fmt package to output variable i, and the result is 255.

It should be noted that when the byte type value is converted to the int type, overflow may occur. Because the byte type can only represent unsigned integers from 0 to 255, and the int type can represent a larger range, if the value of the byte type exceeds the representation range of the int type, overflow will occur. Therefore, in practical applications, data type conversion needs to be performed according to specific situations to avoid overflow problems.

In summary, converting byte to int is very simple in Golang. You only need to call the int function for type conversion. However, it should be noted that overflow problems may occur during conversion, which need to be handled according to the actual situation.
