This shouldn't surprise you, considering that 1/1000 is not exactly
representable in base two.  I thought about this when implementing it,
and decided it was okay because $] >= 3.041 is still true.  (This is
because 3.041 is also represented internally as 3.0409999999...)

If you want to print $] numerically, say printf("%5.3f",$]).
