The final section, ranging from character code 128 to 255, was a more recent addition.Įvery code has eight bits, each starting with one (as opposed to zero as in the previous two sections). In the next section, you’ll find the printable characters that occupy spaces 32 to 127.Īny character you see on the keyboard will be in this group, from the % symbol to the letters and numbers.Įven the spacebar and the delete key have their own codes (numbers 32 and 127, respectively). These unprintable numbers are only to control different external devices, like a keyboard or a printer. There are a total of 32 characters in this subgroup, labeled from 0 to 31. The first ASCII section is a control group that contains unprintable characters. To further organize these codes, the founders separated the characters into two sections, which later became three as people developed codes for more specialized characters. Instead of remembering the byte for each letter, symbol, and number, the founders organized them numerically and assigned them a decimal value.įor example, capital A (as mentioned above) is number 65, while the lowercase A is 97. Well, each byte in the standard ASCII starts with zero, so the following seven digits are those that differentiate the characters. If you counted how many digits there are, you might be confused about why there are eight digits instead of seven. This code is binary, so it only uses a combination of zeros and ones.įor example, the bits (binary digits) for a capital A are 01000001, while the bits for a lowercase A are 01100001.
Essentially, it is the computer’s own language.Ĭomputers have a seven-digit code to represent each letter, number, and punctuation. ASCII ExplainedĪSCII stands for the American Standard Code for Information Interchange. You may know that computers use binary (combinations of the numbers zero and one) to store information, but how does that translate into the comprehensive text you read on your screen? Have you ever stopped to wonder how your computer works? What Is the Decimal Numeral System in a Nutshell?.So if you want to get the complete ASCII to decimal conversion table, then this article is for you. This ASCII to decimal table contains all 256 ASCII characters and their decimal counterparts. The complete ASCII to decimal conversion table.
