I got 2

I got 2 and not 2. in your example. Perhaps, you have either 1. instead of 1 or 3. instead of 3 in q?

convert/rational

This might help:

convert(2.-x, rational);

The other option:

In the interest of completeness, I believe the other option would be as follows:

floatProcessor := proc(x)
local mantissa, exponent;
  mantissa, exponent := op(x);
  if abs(mantissa) < 10 and exponent = 0 then
    return Float(mantissa * 10, -1);
  else
    return x;
  end if;
end proc;

a := x - 3.;

subsindets(a, float, floatProcessor);

This returns x - 3.0. Hope this helps!

The leaf of the acer palmatum (irohamomiji) could inspire a refreshing change for a new logo for Maple.
