So it's okay for "system level programming languages" to produce 
numeric garbage when it comes to floating points? ;-)

Sorry, couldn't resist. Some people keep claiming that D is a 
"system level programming language" despite there is no single OS 
and no single hardware driver written in D yet. Which sorta puts 
D and Java into the same boat. Besides - gasp! - Java *is* a 
system level programming language after all. There are 
platforms/devices which support Java bytecode natively. For 
system programming, it's extra important that the same algorithm 
produces exactly the same results on different environments. And 
the speed is not always the most important factor.
