Subj:   Re: How to convert decimal to hex
 
From:   Janik, Robert B

Hexadecimal is base sixteen whereas decimal is base ten. Hence,

Hex =   Dec
1       1
2       2
3       3
4       4
5       5
6       6
7       7
8       8
9       9
A       10
B       11
C       12
D       13
E       14
F       15
10      16
11      17

...and so on.

Each position from the right to left is a power of 16, so a hex value like "ABCD" may be represented in decimal by interpreting, then adding these numbers:

13        =    13            =   hex    "D"
192       =    16*12         =   hex   "C0"
2,816     =    16*16*11      =   hex  "B00"
40,960    =    16*16*16*10   =   hex "A000"
------
43,981 (decimal) is therefore equal to "ABCD" hexadecimal

Without a hex calculator or an old IBM system reference summary card (know any MVS people?), this is as good as it gets.
