數字系統的表示方式
步驟1:將十進位數字除以8,求商及餘數。
步驟2:若商 ≧ 8,則繼續步驟1,否則進行步驟3。
步驟3:把連除8的所有餘數,由下而上,依序由左而右排列,即為所求。
例:將 (77)10 換算成八進位
G 十進位數字轉換為十六進位
步驟1:將進位的數除以16,求其商及餘數。
步驟2:若商 ≧ 16,則繼續步驟1,否則進行步驟3。
步驟3:把連除16的所有餘數,由下而上,依序由左而右排列,即為所求。
例:將(100)10換算成十六進位
練習 1: 十進制表示法的17在16進制中應如何表示?(1)17 (2)11 (3)10 (4)21。
練習: (將十進位的0 ~ 16 ,計算出2進位、8進位、16進位各是多少 ? )
十進位 0 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16

(甲) 二進位數字轉換為八進位
步驟:將二進位從右開始,取3個一組,解出其值,便得結果。
例:二進位表示法為 1110101011,其八進位表示法為(125)8
(乙) 二進位數字轉換為十六進位
步驟:將二進位從右開始,取4個一組,解出其值,便得結果。
例:二進位表示法為1011101011,其十六進位表示法為(C3)16

Hexadecimal Trivia
A5B is the hexadecimal representation of the binary number 101001011. Hexadecimal is a base-16 number system used in computing. It is often used to represent colors and memory addresses. In hexadecimal, the digits 0-9 represent their respective values, while the letters A-F represent the values 10-15. So, A5B is equivalent to 10*16^2 + 5*16^1 + 11*16^0 = 2560 + 80 + 11 = 2651. Hexadecimal trivia: Did you know that the hexadecimal system is commonly used in computer programming because it is more compact and easier to read than binary?
