Do you take the number divide by 16 the quotient is the 1st charcter and the remander is the second??

 

E.X. [math]173/16[/math] is 10 with remainder 13 so the hex number world be AD right??

Think of how we do the decimal system: hundreds, tens and units:

 

HTU

110 = 1 * 100 + 1 * 10 + 0 * 1

 

We handle hexidecimal in the same way, except we have powers of 16 instead of powers of 10 as our "bits". And instead of just going up to 9, we can use 0-9 and A-E (A = 10, E = 15). For example:

 

16 1

A E = 16 * 10 + 15 * 1 = 175 in decimal

 

Hope this helps a bit, I think the way I've worded it is a bit complex though - mainly because it's 3am and I'm quite tired ;)

To convert integers to hex, just keep dividing by 16. You will get the hex code right to left in the successive remainders.

 

For decimals keep multiply by 16 and keep takin integral part, its'll give u hex from left to right from the decimal point.
