an addition for isnum to incorporate decimal and hex...

currently I check for hex using:

Code:
alias ishex {
  if (!$len($remove($1,1,2,3,4,5,6,7,8,9,0,a,b,c,d,e,f))) return $true
  else return $false
}


which is a very simple and fast (non-regexp) solution...
but since hex is a highly used system it might be nice to have a build in way like isnum

(note: this isn't some high priority thing... just a nice idea which is easely scripted)

If it ain't broken, don't fix it!
