Questions & Answers
Q: What is the difference between hexadecimal and decimal numbers?
Hexadecimal and decimal numbers are different base counting systems. Decimal numbers use a base of 10 (0-9), while hexadecimal numbers use a base of 16 (0-9, A-F).
Q: How do you convert a hexadecimal number to its decimal equivalent?
To convert a hexadecimal number to decimal, each digit is multiplied by increasing powers of 16. The hexadecimal digit 'A' is equivalent to 10, 'B' is 11, 'C' is 12, 'D' is 13, 'E' is 14, and 'F' is 15.
Q: Can you provide an example of converting a hexadecimal number to decimal?
Sure! Let's convert the hexadecimal number 32A. The digit 'A' is equal to 10. So, 32A becomes (3 * 16^2) + (2 * 16^1) + (10 * 16^0), which equals 810 in decimal.
Q: What happens when there is a decimal place in a hexadecimal number?
When there is a decimal place, the digits to the left of the decimal are converted as usual. The digits to the right of the decimal are multiplied by decreasing powers of 16 (16^-1, 16^-2, etc.) to get the decimal equivalent.
Summary & Key Takeaways
-
The video explains the difference between hexadecimal and decimal numbers, which are different base counting systems.
-
Hexadecimal numbers have extra digits (A-F) compared to decimal numbers, which only have digits 0-9.
-
To convert a hexadecimal number to its decimal equivalent, each digit is multiplied by increasing powers of 16 and then added together.
