Convering Decimal Hexadecimal an

16进制的转换是以值 X 除以16 所得的商再除以16 再不断的重复 知道余数为0
每次的余数即为16进制的位数

例
186 = 16 X 11 + 10 A
11 = 16 X 0 + 11 B
186的16进制即为 0 x BA

①

167 = 2 X 83 + 1
83 = 2 X 41 + 1
41 = 2 X 20 + 1
20 = 2 X 10 + 0
10 = 2 X 5 + 0
5 = 2 X 2 + 1
2 = 2 X 1 + 0
1 = 2 X 0 + 1
① = 10100111

②

0111 = 7
1010 = A
② = 0XA7

④

62 = 16 X 3 + 14 D
3 = 16 X 0 + 3 3
④ = 0X3D

③

D = 1110
3 = 0011
③ = 0X111110

⑥

188 = 16 X 11 + 12 C
11 = 16 X 0 + 11 B
⑥ = 0XBC

⑤

B = 1011
C = 1100
⑤ = 10111100

⑧

0011 = 3
0111 = 7
⑧ = 0X37

⑦

3 X 16 + 7 = 48 + 7 = 55
⑦ = 55

a

1000 = 8
1000 = 8
a = 0X88

⑨

⑨ = 8 * 16 + 8 = 128 + 8 = 136

b

1111 = F
0011 = 3
b = 0XF3

c

c = 16 * 16 + 3 = 259
