  I use a serial LCD and use the serial terminal's Dec method to convert. But if you wanted to write to a buffer you could reuse that code inside your object.

  Thanks, I hadn't even thought about FullDuplexSerial's dec method...

  This is a method that I add to a variant of FDS that I use in my projects -- it's especially useful for LCDs that might be used for instrumentation type displays.
  

  pub rjdec(val, width, pchar) | tmpval, pad
  
  '' Print right-justified decimal value
  '' -- val is value to print
  '' -- width is width of (space padded) field for value
  
  '  Original code by Dave Hein
  '  Added (with modifications) to FDS by Jon McPhalen
  
    if (val => 0)                                                                 ' if positive
      tmpval := val                                                               '  copy value
      pad := width - 1                                                            '  make room for 1 digit
    else
      if (val == negx)                                                            '  if max negative
        tmpval := posx                                                            '    use max positive for width
      else                                                                        '  else
        tmpval := -val                                                            '    make positive
      pad := width - 2                                                            '  make room for sign and 1 digit
     
    repeat while (tmpval => 10)                                                   ' adjust pad for value width > 1
      pad--
      tmpval /= 10
       
    repeat pad                                                                    ' print pad
      tx(pchar)
  
    dec(val)                                                                      ' print value
  

  
  Note that rjdec calls the dec method.

  check also the basic number formatting objecs:
  numbers (included in the propeller tool)
  simple numbers http://obex.parallax.com/objects/182/
  
  I really like simple numbers because it is easier to use, and has some formatting options not available in numbers (some fixed format options, for instance).
