In my case and many others, such issue was addressed during first week of introductory programming classes. I was naively thought "computer = precision" and I was stunned to find out the inaccuracy of computer calculations. But as you experienced, I also stumble upon some people (specially Java only programmers) who were not aware of it. > also, argument about raw speed and fine control vs automatic > management, rots with time.

Because 99.99% of computer users and programmers can afford to, and willing to lose such small inaccuracy billion times in exchange for some performance increase and convenience. Although NASA may not accept my application for their projects for Mars mission after this posting.
