Conversion from Octal to Hexadecimal
Converting numbers from octal (base 8) to hexadecimal (base 16) involves grouping the octal digits into sets of three and then converting each group into its hexadecimal equivalent. For example, let's convert the octal number 647 to hexadecimal.
First, we group the digits: 647 --> (00)6 (04)7. Then, we convert each group: 6 in octal is equivalent to 6 in hexadecimal, and 4 is equivalent to 4. So, 647 in octal is equal to 64 in hexadecimal.
This conversion process comes in handy when working with low-level programming or when dealing with computer memory addresses. Both octal and hexadecimal are commonly used in computing operations for their compact representation of binary values. Additionally, understanding this conversion can be useful when troubleshooting computer systems or analyzing file structures.
