Question 1105379
Convert 82.11 to binary
----
the integer part is easy.
82 = 5*16 + 2
--> 1010000 + 10 = 1010010
=============
Assuming you mean just 0.11 and not repeating 0.11.... = 1/9 :
---
11/100 = 1011/1100100
0.11 in binary is repeating.
Doing the long division gives in binary:
0.00011100001010001111
-------
In Hex, it's 0.1C28F5C28F5C28F5C28F... (base 16)
The repeating is obvious in Hex.
82.11 in Hex --> 52.1C28F5C28F5C28F5C28F...
----
Hex and binary are just a matter of grouping.
Each Hex character --> 4 binary 0's and 1's
