I like vimtip #27: 'Convert hex to dec', but couldn't find the reverse function... So I took a whack at it. This function translates all numbers decimal to hexadecimal. Work is needed to better discriminate decimal numbers (e.g. vs. octal).
function! Dec2Hex()
let lstr = getline(".")
let decstr = matchstr(lstr, '\<[0-9]\+\>')
while decstr != ""
let decstr = printf("0x%x", decstr)
exe 's#\<[0-9]\+\>#'.decstr."#"
let lstr = getline(".")
let decstr = matchstr(lstr, '\<[0-9]\+\>')
endwhile
endfunction
Cheers!

I have this in my gvimrc for years (don't know the original source):
20nmenu Editieren.Show.dez->hex :echo "0x".Nr2hex(32)
20nmenu Editieren.Show.string->hex :echo "0x".String2hex("123Aa")
20nmenu Editieren.Show.dez->char :echo nr2char(49)
20nmenu Editieren.Show.char->dez :echo char2nr("'*")
20vmenu Editieren.Show.dez->hex y<ESC>:echo "0x".Nr2hex(@@)
20vmenu Editieren.Show.string->hex y<ESC>:echo "0x".String2hex(@@)
20vmenu Editieren.Show.dez->char y<ESC>:echo nr2char(@@)
20vmenu Editieren.Show.char->dez y<ESC>:echo char2nr(@@)
"……………………………………………………………………………………………………………………………………………………………………………………………
" The function Nr2hex() returns the Hex string of a number.
func Nr2hex(nr)
let n = a:nr
let r = ""
while n
let r = '0123456789ABCDEF'[n % 16] . r
let n = n / 16
endwhile
return r
endfunc
" The function String2Hex() converts each character in a string to a two
" character Hex string.
func String2hex(str)
let out = ''
let ix = 0
while ix < strlen(a:str)
let out = out . Nr2hex(char2nr(a:str[ix]))
let ix = ix + 1
endwhile
return out
endfunc
For example, just mark a number and select dec->hex in the edit menu, hit CR (or add <CR> to the menu mappings),
and you see the result in the command line. A more convenient place for the menu entries could be in the popup menu.

| Oops, the title of this tip must be "Convert dec to hex". ;-)
