Anyone knows how is the equation to convert decimals to hexadecimals?

For example:

41500 -> A21C

I had it written somewhere, but I lost it long time before, if anyone can help me I would be veeeeeeeeeeeeeery grateful!!

Thanks

Well, aside from plain conversion like in a calculator, is this for a program? And if so, what language?
 
Come on, guys... My question was clear.

What is the *equation* used for decimal to hexa conversion. Anyone knows it?

It is for a VB program, why?

I've got a working program in C/C++.

Basically you divide the number by a power of 16, one that divides into the number less than 16 times (or you must choose a higher power), then take that number and convert it to hex (0123456789ABCDEF). Then subtract that value * 16^power, and repeat with a lower-order power.

Ex:
[pre]

for i = 10 to 1, step -1
{
Temp = Number / (16^i)

if Temp = 0, HexNumber:Character(i) = '0'
if Temp = 1, HexNumber:Character(i) = '1'
...
if Temp = 15, HexNumber:Character(i) = 'F'

Number = Number - (Temp * (16^i))
}

[/pre]

I had to make it (i-1) in my equations (but not the for loop) for it to work properly.

Because some of us have source code for certain languages like C/C++.

You may consider using a function like HEX() in VB if there is one. No use reprogramming the wheel.

Or, you could just use a calculator which converts from hexadecimal-decimal and back (you make less mistakes and don't have to memorize long equations).

I can email you the one I use.

I think he wants it so he can program it into his program to give values or actually compute the values to print out to the files themselves.

Windows Calculator works pretty good for me actually.

Thanks

Thanks, Xotor, it's going to be very useful :-)

I can translate arithmetic algorithms from C to VB (it's not very hard, thought), so, if you have any interesting hex code you can show me it (I'm learning C and C++, too)

Yes, but my problem is that I need to save the values to a file in an endian fashion [H] [L], and the Hex() function gives me the full value (eg: FF1CE2) and I don't find another way than reversing the value to save it correctly.
I want to be practical, so if I have to place a byte for every..... no wait......

I have another idea! Thanks!!!!! ;)))))))

Oh, right.

It takes up too much of my screen so I don't use it.
