Great! :-D  But it still doesn't seem to make any difference on my G5 and
may even be slower on my older machine. Maybe it's a surfeit of its
rather than of tells. Mind you, the tells were only there in the first
place to accommodate the it * it multiplication. They're not necessary
otherwise:

  on currency_format for v
    (v div 1 as text) & (0.0 as text)'s character 2 & ((((v mod 1 as
text) * 100) ^ 2) ^ 0.5 + 0.5) div 1
  end currency_format
  
  currency_format for -321.255

:-)
