Hex

  • 16 years ago

    I think this is something to do with hex but i thought that hex was a 2 character thing not 3 (the h on the end means hex).


    I have listed a few of some hex values i think they are some sorta hex
    H - 048h
    e - 065h
    o - 06fh
    l - 06ch
     - 020h


    I am trying to find out what is the equation from ascii code to hex and back or can someone give me a big listing of all the values/characters that could be used.


    Thanks

    if u use vb u can use the "hex()" function to hex the values, to go from hex back to ansi then use the same function but prefix the values with "&h" which should give u what u want.

    hexadecimal is base16, whereas 'decimal' is base10...
    so to convert between the two, just switch bases...


    i.e., one way (longer way) is to do this:


    Hex #'s go from 0,1,2,3,4,5,6,7,8,9,A,B,C,D,E,F
    A-F = 10 - 15
    So if you have a number like:


    08CA, then it is
    016^3+816^2+1216^1+1016^0


    To convert a decimal number from decimal to hex,
    you divide by the largest power,and then carry over
    the remainder with smaller powers.


    I.e., so 2250/256= 8 + 202 as a remainder
    202/16=12 + 10 as a remainder
    10/1 (16^0) = 10 + 0 as a remainder...


    so you now have 8,12,10... you now convert to
    the hex numbering system, and you have "8CA"...!

    thanks but i think that is what the vb function does, so i will keep with that, but thanks for explaing how it is converted
