Hexadecimal to Decimal

Hi

Are there any Hexadecimal to Decimal conversions on the A+ test papers?

If so does anyone know a good explanation, as I just can't get my head round
it?

Cheers

Paul

Re: Hexadecimal to Decimal

/me agrees.

Cannot see why they would want you to convert though - not a great
deal of use. Hex to binary is easy as you just take each digit as a 4
bit chunk.

ie:

3f2f

3= 0011
f = 1111
2 = 0010
f = 1111

chuck em all together and that's a simple binary conversion

0011111100101111 = 3f2f

Then you can go decimal from there quite easily using standard binary
decoding.
