Thanks to all for the help!

I'll remember the assert_in_delta in the future when testing on floats.

The point about avoiding float when doing currency is sound advice, yet 
opens a new chapter of issues when deal with big numbers in special 
pricing units of measure. Then Googled "Class Money" got a spiffy 
"ruby" Money at <http://www2a.biglobe.ne.jp/~seki/ruby/sbpp8.html> and 
a nice interface from junit.samples.money; ah, other have blazed and 
paved the trail.

Thanks.
