Convert Binary To Octal()

Parameters: binaryString (string)

The binary number to be converted as a string

Returns: Equivalent octal value of the binary string as a string

This JavaScript function accepts a binary number (as a string) as input and returns its equivalent octal number. It uses the parseInt function to convert binary to decimal and then converts decimal to octal.

Creating a JavaScript Function to Convert Binary to Octal Numbers

Hello, fellow programmer! You're about to step into an interesting topic. We'll delve into how to convert a binary number to an octal number with a JavaScript function. This essential function can prove extremely useful, especially when dealing with low-level programming. While it may seem tricky at first, with step by step explanation, you'll soon master it. Enjoy the blog post!

Step 1: Decoding the Problem

We want to develop a function that will accept a binary input and convert it into an octal. Remember binary data is represented using 0 and 1 while octal representation involves digits from 0 to 7. Let's start by creating an empty function.

function binaryToOctal(binary) {

}

Step 2: Conduct Binary to Decimal Conversion

Before we can convert binary to octal, an intermediary step of converting binary to decimal is required. In JavaScript, we can simply use the parseInt() function with 2 as the radix to do this.

function binaryToOctal(binary) {
  var decimal = parseInt(binary, 2);
}

Step 3: Conduct Decimal to Octal Conversion

In JavaScript, we have the toString() method which can convert a decimal number into its octal equivalent when 8 is passed as a parameter.

function binaryToOctal(binary) {
  var decimal = parseInt(binary, 2);
  var octal = decimal.toString(8);
}

Step 4: Returning the Result

Now that we have our octal value, we can return this from our function.

function binaryToOctal(binary) {
  var decimal = parseInt(binary, 2);
  var octal = decimal.toString(8);

  return octal;
}

Step 5: Conclusion

The process of converting a binary number into an octal involves first converting it into a decimal, then from decimal to octal. Here's the final implementation of our function.

function binaryToOctal(binary) {
  var decimal = parseInt(binary, 2);
  var octal = decimal.toString(8);

  return octal;
}

Mathematical principle

The binary to octal conversion involves first converting the binary number to a decimal number with the `parseInt` function and then converting that decimal number to an octal number with the `toString` command with base 8. For example: `(1101)2` => `(13)10` => `(15)8`.
