You can define your own format by using

...
CLASS
  ...
  TEXT (round[numbercolumn], 2)
  ...
  LABEL
    ...
  END
END
...

In RFC 64 [1] you'll find some informations.

I'm pretty sure I used it for myself. But grepping through my current
mapfiles say otherwise. So I can't give an working example.
