...you'd be broke.  You NEVER need a loop that runs from 0.0 to 1.0 by 0.1.
1/10 is a repeating fraction in binary, and thus .1+.1+.1+.1+.1+.1+.1+.1+.1+.1
does NOT equal 1.0.  Read "The Elements of Programming Style" for more tidbits
on this and other programming topics.

Presumably this means that it is vital to get the wrong answers quickly.
