有冇人知咩野係16進啊 點算的

16進:
0–9 to represent values zero to nine
A, B, C, D, E, F (or a through f) to represent values ten to fifteen

點算??
so hard to explain this simple thing...

e.g.
10 (hex) = 16 (dec)
becoz
1 x 16 to power 1 + 0 x 16 to power 0 = 16

1E (hex) = 30 (dec)
becoz
1 x 16 to power 1 + 14 x 16 to power 0 = 16 + 14 = 30

16進咪好似一斤十六兩咁逢16進一囉，見到11其實就係十進制既17。如此類推。
