十六進制

十六進制者，基數自十六也，實屬${\displaystyle 2^{4}}$進制，故常用於信息技術。是進制常以A至F代十至十五，亦可記曰${\displaystyle 0,1,2,3,4,5,6,7,8,9,0^{*},1^{*},2^{*},3^{*},4^{*},5^{*}}$

1	1	1
2	0.8	0.5
3	${\displaystyle 0.{\dot {5}}}$	${\displaystyle 0.{\dot {3}}}$
4	0.4	0.25
5	${\displaystyle 0.{\dot {3}}}$	0.2
6	${\displaystyle 0.2{\dot {0^{*}}}}$	${\displaystyle 0.1{\dot {6}}}$
