Are the floating point routines on my machine broken?

[John Cornelius]

The value .2 is an irrational fraction in binary.  Adding the
representation of (irrational) .2 to (rational) +3. results in a
number slightly higher than (rational) +3.0, thereby terminating
the loop.

Henry Spencer is quite right about using floating point numbers
as loop indices, it is a _bad_ practice and has been for nearly
30 years.
