Converting Integers to Binary Representation in Go

Question:

Is there a built-in function in Go that can convert numeric types into their binary number form?

For instance, if we provide 123 as input, we should obtain the string "1111011" as output.

Answer:

Yes, there is an inbuilt function called strconv.FormatInt in the strconv package that can convert integers into their binary representation.

n := int64(123)

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

This FormatInt function takes two parameters: an int64 and a base. The base specifies the base of the numerical representation.
