George,

Here's an improved version of my PrettyNumbers, this one handles cents and
minus, with option to put minus sign to right of number; could easily change
it to put a space between the minus sign & the number, on either side.  The
way it works, could easily make it do <1234>, but I'm not sure whether it's
debits or credits, - or + that you would want to be bracketed.

--------------------------
include misc.e

-- takes an integer and makes a sequence with commas every 3 digits;
-- set 2nd parameter to 0 for normal negative number format (eg:-3),
-- set 2nd parameter to 1 for trailing minus sign  (eg: 3-)

function PrettyNumbers(object aNumber, integer rightNeg)
sequence PrettyNumber, Temp, cents
integer TriCounter, decPos, isNeg
PrettyNumber = {}
Temp = {}
cents = {}
isNeg = 0
TriCounter = 0

Temp = sprint(aNumber)

decPos = find('.',Temp)
if decPos then
   cents = Temp[decPos+1..length(Temp)]
   if length(cents) = 1 then
      cents &= "0"
   end if
   Temp = Temp[1..decPos-1]
end if

if Temp[1] = '-' then
   isNeg = 1
   Temp = Temp[2..length(Temp)]
end if

for n = length(Temp) to 1 by -1 do
  PrettyNumber = prepend(PrettyNumber,Temp[n])
  TriCounter += 1
  if TriCounter = 3 and n != 1 then
      PrettyNumber = prepend(PrettyNumber,',')
  end if
  if TriCounter = 3 then
     TriCounter = 0
  end if
end for

if length(cents) then
  PrettyNumber &= "." & cents
end if

if isNeg then
  if rightNeg then
     PrettyNumber = PrettyNumber & "-"
  else
   PrettyNumber = "-" & PrettyNumber
  end if
end if

return PrettyNumber
end function

puts(1, PrettyNumbers(-123456789.5,1))  -- the "1" makes minus show on right
side.
