# How to use binar, Have You Ever Wondered...

DEL To convert the number for C, 67, into a binary number: Remember how binary numbers are read bottom to top, first position and Default Value to top position and Default Value, with each of the eight character positions assigned a unique number value?

1. Download Step 1: How to Translate Binary The key to reading binary is separating the code into groups of usually 8 digits and knowing that each 1 or 0 represents a 1,2,4,8,16,32,64, ect.

With the chart below, what combination of values would equal 67? So let's change the first, second, and seventh position zeroes to ones, counted from right to left.

Different versions of binary code have been around for centuries, and have been used in a variety of contexts. For example, Braille uses raised and un-raised bumps to convey information to the blind, Morse code uses long and short signals to transmit information, and the example above uses sets of 0s and 1s to represent letters. Perhaps the most common use for binary nowadays is in computers: binary code is the way that most computers and computerized devices ultimately send, receive, and store information. Take a look through the key below and try to spell something using UTF-8 binary code. Try your name!

Here is the letter A as a binary number to represent the ASCII decimal number for A, which is The letter A as a Binary Number If we combine the binary numbers we've looked at so far, we can spell CAT: Bonus: Pseudo-Code to Design a Binary Number Converter With an understanding of how letters and numbers are converted to binary numbers, and back, let's look at how we might create a software application to make how to use binar conversions on the fly.

The application has no real value. But it provides a chance to discuss how a process can be converted to software.

Instead of actual code, however, we'll write up a series of statements or pseudo-code. Let's take the word cat to start.

### Introduction: How to Understand Binary Code

What process do we need to convert these letters automatically into binary numbers? Here's one possible set of steps we could code: Break the word into individual letters. For each binary number, save the binary number value.

If it is the first binary number, create the initial binary number value; if a binary number value exists, add the new binary number to the end of the value.

Imagine if we skipped the last step: what would be the result of these steps? We'd only have the last binary number, for the lower case letter t in cat.

It's important we capture each binary number as they are created. Other observations about this pseudo-code process?

We need to distinguish between capital letters and lower case letters, don't we? Remember, these are eight character blocks of 1s and 0s. Grab a calculator, find the ASCII decimal value for the letter, from the chart above, then look at the binary number chart for the nearest value to the decimal value.

### Decimal vs Binary

Subtract the nearest number Default Value in the binary chart to get a remainder value. Look for the nearest binary Default Value for the remainder.

Repeat until you run out of binary values. Below the binary value of 8 are 4, 2, and 1 which equal 7.

Email If you're interested in learning how to read binary, it's important to understand how binary numbers work. Binary is known as a "base 2" numbering system, meaning there are two possible numbers for each digit; a one or a zero. Larger numbers are written by adding additional ones or zeros to the binary number. Understanding Binary Numbers Knowing how to read binary isn't critical for using computers. But it's good to understand the concept to gain a better appreciation for how computers store numbers in memory.

This also can help convert letters to binary numbers. If your remainder is 7, for example, then you know to put a 1 at the 4, 2, and 1 positions to create that part of your binary number.
