  Not a bug. A limitation of floating point numbers.

  The number 0.1 is pathological in that it cannot be represented
accurately in the base-2 floating point format of the FPU (for the
same reason that for example 1/3 cannot be represented accurately
with a base-10 floating point representation).

  When you add 0.1 like this, the error caused by this accumulates
in such way that after you have added it ten times the result is
not 1 but a tiny fraction less.

  If you use integers only (ie. "#declare Loop = Loop + 1;") then
there's no such problem (because floating point numbers can
represent integers accurately up to a quite big value).
