How to Convert Integers to Binary in Go?

Converting Integers to Binary in Go

Converting numerical values to their binary representations is a common task in programming. Go offers a convenient built-in functionality within the strconv package to facilitate this process.

The strconv.FormatInt Function

The strconv.FormatInt function takes an int64 value and converts it to a string representation in the specified base. To convert to binary, specify the base as 2.

Example:

n := int64(123)

fmt.Println(strconv.FormatInt(n, 2)) // 1111011

Output:

1111011
