In this tutorial, we will learn how to convert a decimal number to binary in Go. We will cover the basic concept of binary numbers and implement a function to perform the conversion.

Binary conversion is the process of converting a decimal (base-10) number to a binary (base-2) number. In binary, numbers are represented using only 0s and 1s.

The syntax to convert a decimal number to binary in Go is:

```
func decimalToBinary(n int) string {
if n == 0 {
return "0"
}
binary := ""
for n > 0 {
remainder := n % 2
binary = fmt.Sprintf("%d%s", remainder, binary)
n = n / 2
}
return binary
}
```

We can create a function to convert a given decimal number to binary by repeatedly dividing the number by 2 and keeping track of the remainders.

For example,

- Define a function named
`decimalToBinary`

that takes one parameter`n`

of type`int`

. - Check if
`n`

is 0. If true, return '0'. - Initialize an empty string
`binary`

to store the binary representation. - Use a
`for`

loop to repeatedly divide`n`

by 2 and prepend the remainder to`binary`

until`n`

becomes 0. - Return the binary representation as a string.
- In the main function, call the
`decimalToBinary`

function with a sample number and print the result.

```
package main
import (
"fmt"
)
func decimalToBinary(n int) string {
if n == 0 {
return "0"
}
binary := ""
for n > 0 {
remainder := n % 2
binary = fmt.Sprintf("%d%s", remainder, binary)
n = n / 2
}
return binary
}
func main() {
// Convert 10 to binary
result := decimalToBinary(10)
// Print the result
fmt.Printf("Binary representation of 10 is %s\n", result)
}
```

Binary representation of 10 is 1010
