ASCII is a character encoding standard that assigns unique numbers to each character. Octal is a base-8
numbering system that uses eight digits, from 0 to 7. In order to convert an octal number to ASCII text, you need to convert each octal digit to its corresponding ASCII character.
Conversion
Here are the steps to convert an octal number to ASCII text:
- Identify the octal number you want to convert.
- Convert each octal digit to its corresponding ASCII character. You can use an ASCII table to find the corresponding character for each octal digit.
- Combine the ASCII characters to form the final text.
Example
Here’s an example to illustrate the conversion process:
Let’s say we have the octal number 157 162 164 165 141 154
. To convert this octal number to ASCII text, we need to convert each octal digit to its corresponding ASCII character:
157 -> o
162 -> r
164 -> t
165 -> u
141 -> a
154 -> l
Combining these ASCII characters, we get the final text ortual
.
